Fighting comment spam

Just in case anyone wanted to know, I modified the writeback plugin so that it's non-standard. Just come up with a word that isn't used in any of the code (to keep things simple) and substitue it for writeback in all of the code. For now, it's a bit of a manual process but it doesn't appear to all that hard to automate (changing that is). It may drive the spammers back to posting via the interface, where fight can be on a more even ground.
