That is, I'm making progress in defending the site against comment spammers. Even if few of their attempted spams succeed in getting posted, the load their automated attempts generate is a burden. Something had to be done to reduce it.
I have a job in place on the server now that tests the load every few minutes, and if necessary, adds additional access rules to stop comment-spammers from submitting their junk to the web server.
The results are pretty good: when the job ran at 06:40 GMT, the load average was 76; and one minute after the blocking rules were updated, the load fell to 24. Three minutes later, when I logged in to check, the load had dropped to under 6, on the way down to the normal (under 1).
Not bad!
