Well, unfortunately I think this talk comes from all servers. I've got a lot of friends on different servers, so I've created various sets of 5-man teams on Magtheridon, Laughing Skull, Kalecgos, Archimonde, Blood Furnace, and Medivh. On all 6, I've gotten the 'hacker/bot/cheater' comment more than once in the first few levels. I'm simply nice and say there's no external program, Bliz has no problem with one person playing multiple accounts at a time, then refer them to this site for further info. Just don't get defensive about it and you'll be alright. Most of the negative comments are probably from those just envious that their mommy and daddy won't pay for them to have extra accounts..
