Ok, so I'll try to explain as simple as possible:
1. Obviously you sell stolen models, so your account will NOT be restored
2. Uploading them again on different account will get you the same result - ban
3. If you feel that you want justice and other thieves you see need to be banned too, you can accelerate that process by reporting those to support using the green [Help] button on the right and include a link to the scene with stolen models and link to the original model.
