Most of the time, people just stop and follow me and don't say anything. A few have said multiboxing is against "TOS." One said it was against the "LUA," that made me laugh a bit. I haven't had a GM convo yet (its only been a couple of weeks). I've opened tickets to say who I am, and that I'm multiboxing, but I've not had a response yet. For the most part, I ignore everyone, good and bad alike. If i stopped to talk every time someone whispered me I'd still be doing Brill quests. That's why I like instance grinding during peak server hours, and questing early morning or late night.
