I thought everybody's twitter feed has an army of bots included. I'm pretty sure a good chunk of mine are, and I'm nowhere near that high level. Some time back I got the impression that bots simply follow the trail of twitter suggestions and the users who show up in the feed for retweeting things from those you currently follow. So the more followers an account has, the more bots will find it.
