I don't want to shut off trackbacks/pingbacks because I do get some legitimate ones, but I also get a lot of pingbacks from scraper sites. However, my plugins do not catch these pingbacks (until I add them to my blacklist) because the pingbacks are legitimate in that the scraper site includes a link to my site so the pingback validates. I use Bad Behavior and Spam Karma 2.
Is there a plugin that will send all approved pingbacks/trackbacks into the moderation queue? I did see one from mtdewvirus, but it hasn't been updated in 3 years.
