About three weeks ago, an upgrade to the latest version of Movable Type killed our comment spam filtering.
I finally had an hour to track the problem down, and it turns out the upgrade cleared the WordPress API key that MT-Akismet needs to function. We’ve restored the key, and comment spam filtering is back in great shape.
During the time Akismet was offline, I was deleting close to 1,000 comment spams a day and our server was getting killed by all the rebuilds — the home page and RSS feed were being rebuilt about once every three minutes.
Thanks for your patience, everyone. I hate spammers.
Update: Looking through the stats since we got spam filtering back online, I’m finding that Gadgetopia filters a spam comment every 42 seconds.
