For a number of reasons that thread is a bad idea. As Bette mentioned, weight talk.
Members are unable to see the removed posts in individual model threads that get nixed any time any
sort of image that really "shows off" a model's body is posted. Trust me when I say, there's always a few.
Not only does it create the potential for lots of weight talk. It also creates the potential for, let's be honest here, the perverted talk, which is also not allowed on tFS. Another problem, the fact that we don't want to emphasize the nude bodies of younger models. We allow girls who are 14 or older to have threads, but we do carefully monitor the subject matter of the talk in the younger girls threads as opposed to someone who is in their 20s or older.
But thank you for asking before you jumped right into creating one, many wouldn't have, and it is appreciated
