It already happened now and then that my blog was hit by spam. The mechanism seems to be brain dead: follow all available urls and scan the retreived document for forms; fill the input fields with stuff like “viagra”, “casino” etc. and submitt the form. So far it was at least annoying, but since comments and trackbacks need to be approved I could remove the spam with a single mouse click.
Today, however, I received about 240 trackback notification mails in about four hours. So, I took the opportunity, upgraded to the latest serendipity version and also modified all available articles to not allow comments and trackbacks anymore. Thats it, spammers!
