I've participated in "raids" that involved hundreds of characters...and more than a few server crashes as a result. If anything, Blizzard actively encourages player-improvised events. If you're not actively trying to crash the server, they're not going to care. And if people lag in cities, well...Lagforge didn't get its nickname over multiboxers. They'll try to improve the rendering engine and so forth to make the game more accessible, but it's not their problem if people can't learn to turn their video settings down to something that works on their out-of-date hardware.

You and Sam are among the very few "full-raid" scale boxers...and there are no rules against opening a portal for your raid back to town after a run. The guy that started that thread is a just a dumbass. A loud dumbass, maybe, but not one that will have anyone at Blizzard listening. Maybe if someone was 300-boxing, there might be concerns.

Just two examples of why there's not a snowball's chance in hell of Blizzard doing anything like that (a little incoherent, but I'm tired, and it's clear enough). Aside from the whole "lead designer used to multibox" thing. Really, since the press over you guys started up recently, I'm getting many positive reactions from players that actually know WTF multiboxing is, and very few "zomg botter, hacker, gold farmer, I'm reporting you to my mommy!" hate tells. It's pretty sweet.
