A very warm welcome Michael, I look forward to seeing your faces.
If you create faces for yourself and do not publish them then they are unlikely to be deleted by the system/admin.
However, publishing faces with trademarks ( unless you own them or have permission to use them ) is against the terms of service and doing so would risk having the faces deleted ( and you could end up being banned if you keep doing it ). It does not matter if you sell them or not, publishing faces that infringe on someone else’s intellectual property ( designs, copyright, trademarks, etc. ) is not allowed. So just keep them for yourself and all will likely be ok.
Having said that, just go wild, come up with your own trademarks and designs, publish them and have fun!
