i’ve tried what i can to eliminate spam trackbacks, but they just keep coming up with new ways to get them through. and i’m sick of policing my blog for spam trackbacks, as many as hundreds a day. so i’ve sadly turned off the trackback and pingback feature. i’ve also temporarily changed my comment moderation so that only previously approved commenters get posted immediately – the rest go into my moderation cue, and once i’ve “approved” them, they’ll get posted. we’re looking into some wordpress plug-ins that will deal with all of this more directly; so hopefully i can reset things to normal soon.
