Spam bots are creating accounts on my music wiki (http://www.blazemonger.com/GG/Special:RecentChanges). What is the best extension to prevent this? I installed ConfirmEdit and tried the default CAPTCHA (SimpleCAPTCHA) but it didn't stop the bots. Before I experiment with the many other options, I thought I'd ask what people recommend.
Fortunately the bots can't edit articles, just create useless accounts.
Thanks, DanB
