Troubles with black lists
So, until today, I had the anti-spam plug-in here at the blog. It basically functions in a way that it compares the content of the comment with URLs from the black lists on the surbl.org and if the URL is found, it redirects you to http://127.0.0.1/ (a.k.a. localhost).
My assumption (and you’re here to tell me if I’m wrong) is that all those lists eventually become filled with legitimate (non-spam) URLs. And that would explain why some of my visitors (thanks to Jens for reporting it) couldn’t submit their comments. All I can say is – sorry for the inconvenience!
