I’m finally sick and tired enough of comment spam to do something about it. God bless Jay Allen for creating MT-Blacklist, which I finally got around to installing. I had been taking the time to individually block IPs as they rolled in, but they are so prevalent now that I don’t have the time.
Denis had installed MT-Blacklist a while back but I never got around to activating it. Silly me. It’s activated now though.
