|comment spam on Movable Type blogs is straining servers
T.Whid has more
This is just going to get worse and worse.
A few comments on this article. Note that this is a CPU load issue and not a bandwidth issue. Computers running Movable Type have to do a lot of work whenever a comment is posted (more than we do here.) The benefit for them is that serving pages is less work (while posting and commenting take a lot more work.) So the comment spam is straining their server resources, not their bandwidth.
For people who are running MT, I would highly recommend renaming the mt-comments.cgi file, and then doing a search and replace on the rest of the MT files and changing any calls to mt-comments.cgi into calls to your new name for that file.
We are still getting hundreds a day, but our filters seem to be doing a pretty job at the moment.
I'm working on some new ideas too, but probably won't have anything finished until January.
