There's a lot of threads on this topic in here, but this one had the most entertaining premise, so this is where I'll say this.
We wage a constant battle against bots. Blizzard has an entire
department devoted to tracking down bots, hacks, and the like, and punishing those who make use of them. In fact, if/when you have something to report, you can email that team directly at
[email protected]. They'd absolutely love to hear from you.
That goes for more than just bots, as well. Exploits, cheats, hacks -- any such behavior you see, send our Hacks team an email. Any evidence you can put together is great as well, video in particular. Toss something up on Youtube (can be unlisted) and send us the link. Make sure character names and realms are included. Getting in-game reports of bad behavior is good, but it's even better to have hard evidence of said behavior.
We probably can't completely wipe bots from existence. We sure as hell try, but the fight continues. We can, however, punish as many of those who use them as we can catch. And the more we catch, the better our ability to detect them gets.
And seriously, if you catch someone in the act, email
[email protected].
(Also, juuuuust to be clear, we did not "create bots to speed up the BG queue process." That's silly.)
