Boosted Mages Have Taken over Zul'Furrak

Here is what Blizzard has to say about Bot detection:

@Kaivax

We use powerful systems to determine if the suspected player is using an identifiable cheat, and our heuristics (which we do not outline publicly) are constantly improving and evolving. But when we examine a suspect and these measurements aren’t out of line, we have to manually gather evidence against the accused player, which can be very time consuming and complex. It’s worthwhile though, because we never want to take action against a legitimate player.

They use powerful systems to prove botting. You can’t tell if someone is botting or not by just looking at the “Who” list. That’s a surefire way to action against completely legitimate players, which should be avoided at all costs.
