We should also make a thread or forum to discuss models or textures or art or whatever that we're not certain of, and allow the original poster to explain themselves.  Because as Bad Faerie said in another thread, she wasn't certain what the usage was on particular models that she was suspicious of, so said nothing.  

With a forum for this, we can put up an entry that is suspicious and several eyes at once can figure it out, and the original poster will be able to have their say as well - it isn't unusual for several similar models to be made, after all, totally independent of each other.  But this should do a lot towards cleaning this site up - not that I think there's much "theft" here, but those that have occured have been very ugly.
