"One funny bit of news I heard there was a furry artist we all know and love (take a wild guess who) was forcibly removed from Brony con LA (My Little Pony fan convention) for selling pornography. The con had a stated PG rating. After being repeatedly driven out of the dealer's room, he tried selling the stuff in the lobby of the hotel, which was packed with families going to and from Disneyland. Eventually he was removed from the premises altogether."
It's rumor-mill material, so take it with a huge helping of salt. The discussion eventually revealed it was Steve Martin, and a later commenter provided info that sounded a little more focused:
"Have it on the word of someone who was there on staff that the artist in question wasn't trying to sell it from the lobby. He was told to remove all the adult material from his table, which he did, putting it either in his room or car. After that, a con staffer was buying some non-adult prints, and in a casual "let's check up on this" way, asked if he had any adult stuff. Of course, artist in question immediately said he did, and that he would gladly sell them to him from his car/room. Nope, sorry, wrong response, thanks for playing. They ejected him."
