Simon Willison: Blacklisting Comment Spam: I got a comment spam the other day. Annoying.
“I’m fed up with comment spam. From now on, any comment I judge to be spam will be deleted, and the domains linked to from that comment will be blacklisted. Any future comments that contain links to those domains will be refused. My blacklist will be made available as a simple text file, one domain per line, at blacklist.txt. You are welcome to grab a copy of that file once every 24 hours and use it as part of your own comment spam prevention system. I will manually approve all domains that are added to it to ensure only domains of a dubious nature end up blacklisted.”
