took me a while to figure out what it was too then one day i seen them trailing in one after another one day from elwynn forest to stormwind. they'd get to a set spot then drop like flies one after another. alot of times the message is a different site. some say they're porn sites also. either way, i never check them out personally. if they can keep hacking the game and get away with doing this, no tellin what'll happen if you log into their sites.
