that is not enough when it comes to some inviduals… like this GhoostLines guy who has now his third account on FAB selling stolen content:
https://www.fab.com/sellers/GhoostLines%20Studio
He changes his email but the name is always same KRISH SALARIA, so it should not be that hard to know it is the same guy when he applies for a trader verification.
I can see that you removed the alien pack and weapon pack he had there (both packs had content ripped from UnityStore), but the account is still on FAB.
