So I got up this morning and checked my email, only to find a bunch of notices that trackbacks have been created on this site linked to some online casino. As if spammers didn't cause enough trouble in email, now they are taking advantage of the trackback API to clog people's individual blogs with crap. I checked the Serendipity web site (that is the software that runs this blog) and apparently lots of people have been getting hit with trackback spam in February. Fortunately they already had a patch to the anti-spam plug-in to help with this. I have now updated this plug-in and turned on moderation, so hopefully this won't be a problem in the future.
