Official Tebex Newsletter that every single store owner got:
Dear Server Owners,
Our goal in Tebex is to help you run a safe and successful game server. One of our key services is around monetization, and as such, we need to avoid conflict with third party brands and copyrights. Although it may be that no infringement of third party rights has occurred, we are currently investigating certain uses of Rolls-Royce, Mini Cooper and BMW names and imagery. Pending further notice, we request that any and all content containing these brand names or which otherwise makes reference to any of their respective products and services is removed from your store. We kindly ask that you act according to this request immediately, and no later than 5PM GMT on March 20th, after which we will be forced to take appropriate action.
More generally, we remind you that, in accordance with our terms of business, you are not allowed to sell anything that might conflict with third party brands and their copyrights in your shop.
If you do not list any products that violate our terms, you do not need to take any action on your store.
We know that this may have an effect on the variety of items you can offer, but do keep in mind that we must respect the legal rights of third parties in order to be able to allow you to continue to monetize your FiveM server.
To add my two cents to this:
Even without that announcement, it has always been illegal to sell things that are not rightfully yours or where you do not have a commercial license.
Tl’dr: You cannot make money with someone else’s product.
