I'm sure I have seen that face before, complete with cat ears, whiskers, and the heart on the nose!
I also seem to remember it related to someone with a severe negative review on here. Whatever it was, I couldn't find it.
Maybe I am mistaken..
Perhaps an idea... When guys write negative reviews, they post the current profile pic of the prossie they saw, then when the prossies profile changes we still have a record. Kind of like a rouges gallery I suppose...
