Don't be so negative. Blizzard hasn't previously acknowledged bots. But if you read between the lines of Bashiok's Poll post, you'll see that he has acknowledged it tacitly. The bot problem keeps on getting larger and larger. I think it's beginning to reach that critical mass that influences a business decision.
I really hope you're right, 4th...don't want to think they're just throwing a poll up to make it LOOK like they're attending to this community. It's so much easier to scribble a different calendar date for reset, than to implement a good anti-bot solution.
