I suggest looking mods which make use of the StopForumSpam blacklists or writting your own to use their API. They're pretty effective.
Not recently. I had to disable a StopForumSpam mod on my forum because it stopped working. Tons of bots were registering and the IPs and usernames were not in their database.
I switched to a random Q&A to keep the bots out - the only spammers who have gotten in was a guy with two accounts who dropped a tag-team "question" and "answer (with link)".
This whole thing is so annoying, really. Such a waste of our time. I wonder if anyone has been able to estimate the payoff these guys are getting with their infiltration into forums. Logically the payoff has to be high enough for them to keep it up; but I just wonder how worth it it is.
