I mean, ClueBot NG over at Wikipedia does it with relative accuracy, but it's also not an AWB bot but programmed in Python and stuff. And it has a mechanism for reporting false positives that is probably more effective because of the sheer size of the wiki it runs on.

Its own FAQ does mention that anti-vandal bots are the most likely to make mistakes (versus, say, a bot that tags all pages missing certain categories--a monotonous and fairly exact task that's hard to screw up).
