Same thing happened to me... Banned them unbanned three days later... 7 years multiboxing with the same hotkeynet setup.

It's getting harder to identify who is multiboxing and who is botting with that many standstill instant respawn spots, the bots rarely gets reported because they are "hidden" in the open world farming like the Nazmir spot phased for the aliiance, in the other way are the multiboxers, doing quests, walking in the city, crafting etc and are reported in mass from the players...

I reported many bots and they're still there farming because I can't flag them for a review, Blizzard needs to adjust they report and punishment system, or more and more inoccent multiboxers will get banned unfairly.
