A simple question!

Instead of sharing free models which is a really bad investment I noticed that blogging connecting with people and helping others with their work is a far better use of one's time. CGT is the only website that boosts your score when helping other people in the 3D community and that is why it is the best!

Sharing free models worked only at the very beginning when CGT opened because there weren't so many good free models out there. Now just like anything else there are too many to pick from and so if you share your free models they will get lost in the black hole that is the internet.

Some free loaders will see and steal them but they will also only see them 1 time. If your models are seen by real interested buyers they will see them many times and if they buy they will share your info with their friends before they buy and then your views will go up faster.

Use social media like Facebook, youtube vimeo twitter pinterest etc... to get more views and boost rep. That is a far better use of your time and will improve the overall chances of selling.

Thanks bro and I'm really sorry for free models and if I delete my free models, what will happen? I mean my reputation point will decrease or something else? Thanks once again...

Do not delete your free models just sell them at a price even 1 or 2 dollars is better then just giving it away. If you give it to someone that's ok but it should be a friend or someone who already bought one of your models or someone who contacted you personally and wants to see the quality of your models before he buys something from you.
The problem with just having the models for free out there is that only free loaders will look at them the serious buyers will not and then you will get the reputation of someone who is not serious about selling.
I made that mistake a long time ago and it really did not help my sales.
