No more trackback spam
I installed SpamLookup yesterday, and I am quite impressed. It has elimiated all of the Trackback spam that I have been getting.
About 4 times a day I have been getting 5-20 trackback pings for poker sites and various other immoral enterprizes. I have had to log in, and use the MT blacklist plugin to remove and blacklist these websites.
Spam lookup blocks all of those automatically. When it recieves a trackback, it verifies the IP of the transmitter, and makes sure that they match the IP of the website. If not, it discards the Trackback. Pretty slick. Saves me quite a bit of time and annoyance.
