I do make use of IP blocklists for my mail server, but email spammers
are a different kind of animal from wiki spammers. I would be very
reluctant to use any IP-based list for detecting wiki spam because
the IP in question is the IP of a browser, not of a supposed mail server.
However, there is a different kind of list (which I also use on my
mail server) used to check URIs in the message body:
It is very effective in a mail server environment, but I am not sure
how well it would work in a PmWiki script, because there is a lot of
preprocessing followed by a DNS lookup. Implementation details are on
the SURBL site.
I have implemented what I call an "idiot CAPTCHA" on my site. It
consists of an edit password prompt that includes the password. It
would never stop a human or even most chimpanzees, but it has stopped
the spammer who seems so intent on everyone buying cheap drugs.
When the bot gets re-written to look for passwords in the prompt,
I'll move to some other technique.
