I’ve been absolutely getting pounded lately with spam comments from spambots–to the tune of one spam comment per minute. That’s filling up and slowing down my database and consuming CPU resources that I want for human readers.
So I resorted to installing Botblocker. All I can report right now is that it seems to be working–no spam comments for several hours.
I can’t guarantee it will work forever, and I’ve got Akismet to hide whatever spam gets through, but so far my server seems less busy and more happy, which is good. Things had gotten so bad for a while that I was getting timeouts when trying to post, which is ridiculous.
