I decided to make a separate page for requests since the original post is going to get buried eventually. If you have a celeb you'd like to see faked just leave a comment here. I can't promise I'll get to every request, but I'll do what I can.
While I don't personally object to underage fakes, they're illegal where I'm from and I'd rather not take the risk. There are plenty of other fakers who do them, so go ask someone else.
