I do not know about the measures of other sites, but I have seen violations of their rules. It would be good to join forces, and also sellers should join forces.
My proposals are directed mainly to CGT, because they are the ones that have the means to (allow / avoid) disseminate the fraudulent models, and therefore the obligation and responsibility, but it seems that they are not interested. If they do not put filters to detect cheaters and do not prevent them from re-entering again and again, (*) this will never end, or rather the cheaters will end up with this.
Things that sellers can / should do:
- Protect the render with watermarks, logos ... The cheaters are very vague and often do not hide them, so it is easier to detect them.
- Make original models, that come out of your imagination, with original textures, so if you see one like yours, surely they have copied it. If you make a car, of the same make and model that many others have made, and above there are no images of the mesh, it will be impossible to know if it is the same model.
- Put the files in a .zip with password and send it only to the buyer. The password can be changed in each sale, which would allow knowing the origin of the filtration. You can also include some lost comment in a certain line of the .obj file, or some script .., although it does not help much, but something may help, because they do not bother to update the files, today many models are published in 3ds max 2009 - 11 -12 ....
- Read carefully the rules of the different websites selling models and not publish the models on websites, with licenses that allow, that those same websites resell the models. I think that many of the models thus reach the pages of free downloads and many have watermarks of the websites of origin, or are distributed as collections of those webs.
- Send complaints to Internet providers of illegal websites. If we face each other, our complaint will sound louder. Even smaller animals such as ants, for example, if they are united, are capable of doing great things, such as forming bridges to cross rivers, or building large anthills.
- Lose a few minutes to check if our models are on the web, and take a look at the models just published here. There are very blatant cases, it has always been said that 4 eyes see more than 2, and we are many users (and many eyes), that does not happen to us as bluebird com.
- Communicate to the original author (whenever possible), any infraction that we detect, he can demand that the files involved be removed, before 48 hours and he has the right to decide if he undertakes other actions. If the author is not known, but the model violates the rules because it is not original content, it must be communicated directly to CGT, providing evidence.
- Report, because the law is on our side and so the cheaters, will think twice before doing it again.
Things that CGT should do:
- Prevent that you can have more than one user (silence on this topic, I interpret it as if it is possible and that favors cheaters).
- Do not allow more serious offenders to reopen account, and for the rest of the offenders there is a time scale based on the percentage of fraudulent models and the seriousness of the infraction.
- Make the real name and the country are always visible, to prevent cheats can camouflage and open several accounts.
- Request the current license of the software used, when registering as a seller, and that only formats backed by licenses can be published. (This would prevent pirated software and student licenses). There is a lot of fraud here, too.
(*) Sometimes, not even close the accounts, only the models are deleted, but they retain the reputation, views likes .., won with their stolen models and so they can reload their models in batches quickly. I'm still waiting for you to respond to me because those accounts have not been deleted.
