I believe the one available on this site, is one of the best.
Haven't used it myself, but if I ever wanted a triv-bot I would try this one out.
TrivBot2001v2 Speaking from personal experience, I have used this one (even though it uses mirc 5.91), and I've seen it in use on countless channels on undernet, efnet, dalnet, and rizon. Highly recommended (even for learning how to make your own). There is (was) an updated copy edited by Watchdog (here on the forums) that used mirc 6.03+ (but the link I had to that no longer works (maybe he'll give us another link someday, or let someone else host it).
