I think somebody started a thread some time ago about changing attitudes towards multi-boxers over the past 6 months or so, and I've certainly noticed it.

When I first started multi-boxing WoW in April 2007, I got an uncomfortable amount of hate and attention, even on a PvE server, where what I'm doing has very little affect on other people.

In the past 3 months, I think I've had ONE negative whisper, and that was just an indignant "cheater!!!!!", the sender of which was quickly enlightened.

Basically, the anti-multi-boxers have done an amazing PR job for us by continually making inane threads full of asinine arguments that make them look like rabid lunatics while we're all perfectly rational and sensible individuals (*cough*)
