I have changed the settings on this site to allow trackback links. That type of “comment” has been previously routed to my spam folder, in some cases with good reason. But I’d like to see what happens when I allow them. I’ll watch them for a few days. I may find that they’re beneficial (create more traffic to this site) or not. If it turns out that they’re just too “spammy”, I’ll shut them down again. I will also shut them down again if I have to spend any appreciable amount of time removing porno trackbacks.
