"Can't sell hacked avatars" feature

Lately Kogama has had tons of people selling hacked avatars, there is no feature to block or restrict this. There should be a feature that automatically blocks you from selling the avatar if it detects that blocks are placed outside the limits, it should allow 1 block over the restriction in the bottom part of legs because in the BR server if you buy a default tourist the bottom part of the legs go 1 block over the restriction in the top and bottom

Also, people are using the No Texture material just because it has the dog paw and text, if the texture was replaced with a gray texture nobody would use it anymore and the whole problem would be fixed
