It seems that Jay Allen has shutdown both MT-Blacklist and the 'master blacklist' due to bandwidth problems caused by either a denial of service attack or inconsiderate developers.

Jay hosted a regularly updated file of regular expressions that powered the MT-Blacklist comment spam blocking add-in for Movable Type 2.x. He also published a changes feed that made it easy for others to update their own black lists using the master feed. Unfortunately some developers ignored the feed and simply pulled the whole file all the time and just recently this issue has escalated and led to severe bandwidth usage and denial of service as server hosting the blacklist struggled to cope with the demand.

I first noticed the problem yesterday when the automatic failure emails that I get from my auto update script started coming once an hour rather than once in a blue moon. My blacklist here was updated hourly from Jay's feed using, a script that grabbed the update feed and integrated the updates into the local list. This morning, when the updates had been failing consistently for almost a day, I checked up on Jay's site and found the news. :(

Jay, thank you for all your work, it was appreciated.

Looks like it's time to upgrade to Movable Type 3.2.


Have you considered migrating to another blog type?

I (and another guy) maintain a Movable Type based blog (version 2.661). We get a lot of spam, and although mt-blacklist helps, it is very slow and tedious.

We will probably move it to Wordpress soon

I may do. I expect I'll migrate my ski blog to MT 3.2 first and see how that goes.

I'd be interested in your experiences of moving from MT to wordpress; will you blog about them?

Sure. I will add a link here when it is done.

So far I have an installation of Wordpress running on SimplyMEPIS (debian-based linux) in a Virtual PC VM on my Windows XP home maching. Just for playing around and getting familiar with Wordpress (although I haven't had much time for this).

The real installation will be on Windows.
