Why did the Gnome get kicked out of the nudist colony? ... Because he was always sticking his nose in everyone's business
I was doing some pet battle farming a week or so back and my bot had gotten stuck overnight, when I woke up some random player named Blizzgm or some such had whispered me and said I was in violation of ToS for botting and should open a website and give them my account info or some such. Which I of course did not. I just ignored it and continued botting. This, however, means that scammers/goldfarmers/hackers have bots that check who's been where, when and for how long et.c. and try to scam them with scaretactics pretending to be blizzard
Or they just blanket send that message to everyone, and you're part of the statistic that would be shaken by it.
