When I used to use my previous account, I realized that very few trolls actually read anything. They don't read signatures, they don't read profiles. The ones who do read signatures and/or profiles ended up writing me to inform that if I wasn't here looking for a big penis to change my life and make it complete, I should leave. Usually they did this with poor grammar, and zero spelling or even communication skills.
When I changed my user name, and neutered my profile, It took me a few months to realize that trolls also don't read the boards- especially not Etc., etc., which is where I post primarily. I used to freak out every time someone indicated my gender (correctly) in a thread.
I'd hate to go back to the way things were under the old account. AlteredEgo hasn't received a single unwanted private message. The chat room is very different when people assume that you are male. Without lying, I was able to have the most incredible conversation about wet dreams. Sometimes, someone who has been sending me messages in the chatroom will become angry when they find out my gender. They become angrier when they are forced to admit that I never decieved them. Other than that, nothing unpleasaant has gone down. I highly recomend going neuter to anyone with troll trouble. The only drawback is people are more reluctant to talk to you because they think whatever baloney they have in their profile is telling you something about them (which USUALLY is NOT the case), and want the same baloney from you in return. I have found that to be an acceptable cost.
