I?ve only got Battle.net friends in my main account, which I don?t bot except for a few dailies and not much more. Anyway, those are RL friends from before WoW started and that already knew I was botting, so it?s no problem. We even make some jokes, calling my bots "my autist brother" (doesn?t talk, just does repetitive moves, quite relaxing for him ;-P)
Actually, I remember this guy in our guild, he had some suspicious connections without saying anything not even responding, and I went like: "Mmm... perhaps he?s got an autist brother!" and they bursted laughing, hahaha! I guess the rest of the guild didn?t understand anything (and probably some of them were quite offended xD)
