I have run this experiment in several communities, including Xbox Live (which is full of annoying teenagers). My experience wasn't much different from choosing my normal male-coded nicknames. Instead of assholes calling me, "fag", they called me "bitch". Also I got more comments related to sex instead of violence. I didn't keep track of actual numbers, but the amount of harassment and trolling I received felt about the same.

Apparently a Pew poll came to similar conclusions. The only area in which women reported significantly worse harassment was regarding stalking. On the other hand, men were almost twice as likely to be physically threatened. It really seems like a wash to me.[1]
