It's a certain dealer who sells them, and they haven't been at Fanime for a year or two from what I have seen.... However, there is a game that goes with the yaoi/yuri paddles, involving spanking people and getting them to make out or have someone else make out with them. If they refuse, they get harassed until they do. It's very rude and disrespectful, in my opinion, and can be considered sexual harassment, so maybe the dealer hasn't been asked to come back because of this? I don't know. I've seen people with the paddles walking around, but they bought them from AX and weren't asked to put them away or anything. So, I don't think the paddles themselves were banned, but maybe the dealer just doesn't work at Fanime, or maybe they can't sell the paddles any more due to sexual harassment. I don't know.
