It's my impression that a lot of spam comes not from bots, but from people
in China or elsewhere where labor is cheap. Seems like antibot techniques
won't help there -- you'd need smarter software...
I can confirm that. My (Best Practical's) wiki has been getting pretty
hammered. Adding captchas didn't even slow them down. Turning every
external link to "This link blocked due to wikispam" didn't slow them
down. And the sad thing is that since kwiki has a regexp based parser,
when they paste in 20k of hyperlinks with chinese hyperlinks, the page
won't even _render_ anymore. So it's not like they're getting google
juice from me :/ A couple even left nasty notes saying "you keep
fighting the spam. We're just going to keep hitting you. Give up."
At this point, I'm leaning strongly to requiring email verification for
editors.
