I deleted all of my 3D models from this place last month and I immensely regret ever posting here. What a huge mistake.
They basically publicly state that they will steal artists work and they expect to keep the ship running. Thanos, one of CGTrader's employees stated that they plan to use all free 3D models posted on CGTrader as their own and redistribute them through their AI platform.
Additionally, they switched everyone to AI by default and they manually had to opt out. Which doesn't generate trust. Posting here is the equivalent of giving your 3D models away for free. They can be used for AI and sold for peanuts. That is if they give you peanuts.
There will be a lot of alternatives.
