Ah, it never ends.
Now the spammers are spamming my site by posting Trackback spam. Trackbacks are a way to link between several blogs. Apparently I can close a post to comments, but not trackbacks. Hence they are using trackbacks to spam me now. It's pretty damn obvious that they are doing this though. I get an email for every trackback or spam, so I can easily delete them.
Nice try guys, but it won't work.
