His Gruberness has written, on behalf and with the input of, Six Apart, a comprehensive guide on weblog comment spam. This has given me some ideas for moving forward, though since I have instituted comment registration via TypeKey, I haven’t had a comment spam problem. Registration through TypeKey is free, easy, and fast, and it allows you to comment on any site which supports the protocol.
