Seems like you'd be better off just emailing your findings to Twitter, rather than trying to report each individual bot via the API. These findings could also help them improve their detection. Seems like having a human examine any account with a gibberish name, copied tweets/profile info/photo, and/or following other suspicious accounts, would help a lot. (Of course never automatically close an account for such reasons, only mark it as "hey, one of you admins should look at this and make sure it's a real person when you get a chance".)
