While I agree that bots are a huge problem, I fear that going on witch hunts for bots is going to catch a bunch of MB aficionados in the crossfire.

It happened to me in WoW. Someone reported me as a bot because I managed to take their market away from them and dominate it for the 4-12 hours a day I was on. Bliz in their infinite stupidity simply banned my account without doing any research at all. I DID eventually get my account back but it was a horrid process. I wasn't even using TSM. I was just checking the AH between each activity and adjusting prices. So maybe every 30-60 minutes.

Be careful who you report. Be VERY sure they are indeed bots. There are people out there who like I used to be live and breath for the MB. Some of them might be hard to distinguish from a bot.
