After being deluged with the stuff for a long time, I haven’t received any trackback spam ever since the “upgrade from hell”:http://www.polytropos.org/archives/2005/03/polytropos_rebo.html. MT-Blacklist is now doing its job, but it struck me that there may be other people who, like me, missed the step it takes to get it to work.

So, if you run Movable Type and MT-Blacklist and trackback spam is whomping you big time, make sure that Blacklist is, in fact, updating itself from the Master Spam List every day. _Clicking the box on the config screen is not enough_. Click on the little help icon next to that config option to find what else you have to do. Once that stuff as set, you’ll be blessedly spam-free again, I hope.
