Brace for impact: movabletypo just got hit with its first wave of trackback spam. Some of you may have noticed by a deluge of e-mail this morning. Trackback spam is a bit more insidious: MT doesn't make it as easy to see and cleanup trackback spam as it does comment spam. If this attack continues, we may have to turn off trackback on older entries.

Update: I ran David Raynes' mt-close script on the movabletypo installation to turn off trackback on older entries. I'm sad to see a feature like trackback crippled like this, but as an e-mail conversation this morning pointed out, with sites like technorati as well as Bloglines' citation search, trackback is not as necessary these days.
