I get very little comments now, and they are mostly positive. My server has a very strong majority of Horde, and I'm playing Alliance, so most people cannot comment anyway. I have quite often Hordies starting nice emote-communication in Dalaran.

And the haters ? I reply if they are somehow polite, otherwise I start my multi-characters macro quoting GM posts about multiboxing being legal, and inviting them to report me if they think I'm doing anything wrong.
