I have allowed only registered users to post comments in my blog, but I'm getting more than 20 spam comments/day catched for moderation by the name of "Trackback".
I supposed that with that option turned on, such spam comments should never appear, since they are being posted by non registered users.
I m really not sure why this is happening? It took me so long to make a useful site and now spammers have made that look so bad.
Thanks in Advance
