My RBL-based comment deleting script seems to work pretty well, except that a lot of the RBLs which the spammers appear in are RBLs that list dial-up space, and obviously that’s no good, because while dial-up IPs should be sending mail directly, it’s quite reasonable for them to browse the web.
So I thought, why not create my own RBL listing IP addresses known to spam blogs?
After failing to come up with any particularly convincing reasons why not, I did.
At the moment, it’s a pretty simple mysql database which outputs data for rbldns every half hour. Entries will expire after two days, although I will probably change this (including making it so that IPs get listed for longer the more they show up, etc).
Currently only I can add IPs to the list (they expire automagically), but I shall create a patch for the comment moderation page in WP so you can “delete and report as spam” to automatically submit the entry to the RBL.
If you would like to try the RBL for yourself, stick rbl.jamesoff.net in your RBL list.
(Usual disclaimer about this is my list and if it deletes something you wanted bad luck etc :)
