Dumping on superior models

Why not? (if this is not stolen models). If pricing isn't regulated by CGT terms, modeler\designer\seller is free to appoint any price. Designer is trying to reach at least dime on overcrowded market.
However, the method of selecting models to display on the main page looks very strange.
Honestly, your words smells like the Envy. But from other side I know what is to have quality made models and have no chance to sell it with fair price, because somebody placed some similarly looking shit with the price of matchbox.

For example I tried to set different prices on my models. And concluded: there was no correlation between price and sales. And completely no sense to placing free models (they rapidly appears after it as commercial models and without any respect or gratefulness from downloaders... whatever, it's another theme... )

...and as designer making items for real life I don't understand, why fVking LOW-POLYS for useless games and spammy AR-apps are so overpriced. (It's my own ENVY, yes)

Things are very simple - 99% of all non-Blender, high quality models, that are sold for very low price are either stolen or made with pirated software.
Normal person who invested in software licenses and education will not sell his hard work for peanuts.
Nor will waste his time modeling something complex that already exists in the market with the purpose to sell it heavily underpriced.

"Normal person who invested in software licenses and education will not sell his hard work for peanuts. " -- totally WASP-ish hypocritical bullshit. Nobody is secured about bad or good future. Sometimes people can have troubles.

It's MARKET. We are living in the world of "free market", and here is no sense to cry about dumping or to asking "moderators" about some rules or protection. Market is moderator.

And it's not related to the software price nor software legal status.

Man, I have no problems. You can blame me in drug using (and YES, BUDDY, I LOVE TO SMOKE and doing it a lot).
I'm understanding your problem. But you don't understanding that it's not a problem at all.

I don’t know how it will affect the price of providing evidence that you have licensed software, this restriction is easily bypassed. For example, you can upload a model in formats that a free blender supports, but all sales sites have free format conversion services, i.e. any format will be made to you, even if the seller has not provided it. Something like this, I think if you think about it, you can find many more schemes how to circumvent such restrictions, it seems to me that something else is needed here.

And long story short:
If anybody have doubts about stolen model selling, there is button with three dots (called "Report model"). And if you have proof that model was really stolen, just report it. CGT admins and moderators doing they job very well. They helped me lot of times.

Unfair competition is one of the big problems we suffer here (and in all 3D markets). It is directly related (among other things) to unlicensed software (or student license) and to stolen models. It is easily demonstrable, it is harmful and that is why it is illegal. CGT should end this immediately. It is unacceptable that it is boasted about it publicly. In many countries there are laws against unfair competition, including the US and the EU, and agencies that can be called upon to report. These agencies are independent and can also act on their own initiative. It is time for ALL of us to join together to fight this.

The idea of ​​asking for software invoices seems to me to be a good idea, easily implemented and already contemplated in internal standards. Many of the users with stolen models have inconsistencies in the file formats (different software and versions for each model, almost always obsolete), which are either pirated versions, or will not have the indicated software. Sometimes, there is not even a native format. The simple presentation of the invoice in the process of registering the seller would eliminate many of these problems and obviously regulate the prices. We would all win.

Another example: 11 quality models, which the original author sells for more than $ 1,000, this user sells them for $ 2

https://www.cgtrader.com/3d-models/vehicle/motorcycle/11-vehicles-3d-models

It is shameful. If I had invested a few hours in making them and a few dollars in licenses, I would not sell them at that price.

Another example, could be the user who has been asking in the forum for several days how to modify a DAZ model, I suppose it will be to hide the evidence. In a few days it may be on sale for a couple of dollars. There are many cases of these. That is why mesh catches are important and in any "premium" model they should be mandatory. What translated means in ALL, because here, everything that is not free is premium, although the truth is, as far as presentation is concerned, most suspend (without any information, few images or 1 repeated several times .. )

As long as this type of thing / people is not finished, the market is doomed to extinction, such as telephone booths. Those affected, especially those most affected and with such obvious and substantial evidence, should denounce, because in addition to the economic compensation (high in their case), it would serve to make people aware of their rights and obligations, and of serious consequences that these behaviors can have. If the cheats go unpunished they will not be long in coming back.

CGT should also move token, as an affected part that it is, (like all of us), it would be a strategic movement that would attract quality buyers. Because let's not fool ourselves, those who buy quality models for prices far below their real value, know perfectly the dubious origin of the model, and that is also a crime. It is not the ideal type of customer for any business and also leave little benefit. They are like those who go to a restaurant, but they take the food from home and only consume a soda, the owner of a luxury restaurant would not allow it, but maybe the one in the neighborhood picnic area, yes.

They miss original and quality models, probably good modelers have looked for something more profitable to do. Many of the new models that are seen every day are neither new nor quality, because they have been going around for years (and decades) around pirate pages. Even some of the modeling assumptions are not even, and the accounts are used for other things. All this hurts us all greatly.

Can you elaborate how having trouble or good/bad future is related to what I said?
There is direct correlation between pricing and piracy and that is clearly visible.

If you can't afford expensive software, there is Blender and loads of free tutorials.
Nobody is forcing you to steal - you have a choice.

And you have some really weird comprehension on what free market is.
Free market doesn't mean you can sell everything you steal.

I personally don't think there is a need prices to be regulated.
If 3D marketplaces make it a requirement to present an invoice for purchase of the software in order to be able to sell files made with it, you will see how the pricing problem will be greatly reduced - for the exact same reasons I stated on my first post.
3D Stock Photo sites are already doing this check for renderings of interior scenes, so this will inevitably come to 3D marketplaces as well.
This will solve a lot of problems like this one.

What????
So using stolen tools in whatever bussiness is OK?
I can steal car and operate a taxi service with it?
Are you serious or under influence of some drugs?
And you are publically writing here that you are thief and you have no moral problem with it?????

It's just a silencer is it not? a cylinder with auto metal edging in substance painter and a basic grid like normal for grip. My torch took less than 1 hour to make and I was encouraged to make free models to boost exposure (ofc didn't really work) But not sure what the big deal is tbh there are better examples.

The example on top is not the best, we are talking about things like this:
https://www.cgtrader.com/bomova

Look at the cars (3DSMax + V-Ray) and the prices.

Legitimate user who pays for his software wouldn't even think about putting such price on a model that takes weeks to complete.
If, for example, he is on 3DSMax subscription , he should pay €254,10 per month only for that and he will be losing money with these prices.
There is also V-Ray, PhotoShop, SUbstance etc.
Making 3D models is not cheap if you pay for your tools and if you see such price this is clear indication that something is stolen - in this particular case the cars are from Evermotion.

And another notice about false logics "if you invested lots in the tools, then result can not be sold cheap".
When you are investing in tools some amount of money, you must to know, that this don't guarantees further success. When I operated with park of 3d-printers, for me was very clear: this expensive gear is't intended to recoup itself. But this gear gives opportunity to made product or service that pays todays needs of workshop: to pay taxaes, to share salaries to workers etc. And this scheme works. But if you have ambitions and vanity to get back your investitions in this machines, you will fail (at least without asking and getting help and protection from regulating institutions, but this more smells like false qusi-communism, it's not true free market).

So if you are investing big funds in gear, better if it's your funds. And if you are investing in something by taking loans or borrowed funds, then you will be nervous and will ask help of "big brother" every time when somebody will afford smaller price than yours.

And it's not only about gear, but also about software. It's real life, not MBA-Narnia. And in this real world subscriprion-based business model looks as scam and evil.

"When you are investing in tools some amount of money, you must to know, that this don't guarantees further success." -
Well, of course there is no guarantee, there is no guarantee for anything in this life.
If you are afraid that you will fail, you just don't start.
That is no excuse to steal software.
If you are confident in your skills you take the risk, invest and either fail or succeed depending on your skills.

I also don't like subscriptions, but I'll not judge if they are good or evil - the creators of the software decided that this kind of payment is best suited for covering their expenses and investing in further development, and they have the full right to ask their price, just like you have the right to ask the price for your creations.

In the real world, there are laws, and if you start a business without a license, for example a workshop, and traffic with stolen cars you may end up in jail. If they stop you in a customs house with counterfeit material the same. But unfortunately EVERYTHING is allowed here, which does not mean that it is not still ILLEGAL. By your words it is clear that you do not respect anything and that you have already had problems with important brands (which have resources and a great team of lawyers, in addition to the law on your part). For sample, an extract of the description of one of its models:

"This replica is good enough to not be a fake. (Or it's just free mock to theme of wedding bands with bolt heads blah blah blah). Logo to the shank (and to the special layer) was added just for fun. Anyway jackals from Richemont holding (Cartier, Piaget and lots of another shit for rich donkeys) will report this model with and without logo as copyright infringement because this bastards PATENTED bent nail (!!!) and bolt or screw head (CAAAAAARL !!!). But I'll place this model here again after next blocking. "

I do not understand how CGT no longer takes care of the image of your business. And even more when it can legally splash you. Soon CGT will enter the category of illegal download pages, if you continue to allow these things.

And if talking not about dumping but about "stealing" and other copyright issues, i can say about pair examples:
1. Couple of years ago Turbosq. banned all models of Ford vehicles, because that was "legal" will of Ford Motors.
2. Disney. They always was idiots and are showing disneyish idiotism again:
https ://www.ign.com/articles/2019/11/24/baby-yoda-gifs-removed-over-disney-copyright-issues-star-wars-the-mandalorian-mando?amp=1
In the same time not only CGT but any other stock affords lots of star wars models and other popular stuff.

It's a very nice looking texture, but I think the only thing for sale there is the silencer. So the model itself is actually just a tube consisting of around 300 vertices if that. The only real work involved there would be to paint the texture for PBR (substance painter most likely). $3 seems a little low for the work that went into painting the texture maps, but not unreasonable. Especially if the only thing for sale there is the silencer itself. However, this brings up the question of advertising ethics, if that is in fact the case. Is it honest to show only renders of the entire weapon and other items if the only thing you get in the download is a cylinder with some nice PBR textures?

Damn it! What a fool I am, I thought that this is the whole AK machine, I'm a nerd :(

"...a requirement to present an invoice for purchase of the software in order to be able to sell files made with it"
YOU MADE MY DAY, DUDE!!!

"There is direct correlation between pricing and piracy and that is clearly visible" -- words , empty words of naive enthusiast.
I'm worked and still working using both of tools: legally gained and "pirated". I'm not shy about it. And this doesn't means that my models made with "cracked" software are worse than any other or that other "legal" models are better.
