I am sick of these spammers putting trackback crap. My system doesn't allow trackbacks nor comments, but I have over a thousand filling up my database anyway. When I move fully to my new server, I plan on converting it all to a non-public wiki anyway.
To clean yours out:
Go into SQL, whatever way you normally do.
use blog; <-- yours may be different of course DELETE FROM bB_comments where type = 'comment'; DELETE FROM bB_comments where type = 'trackback';
Now to stop them: Go into the bblog directory:
mv trackback.php trackback_disabled.php
I'll update this later if there's more.
