Track backs are back on, but with moderation
I now have worked a bit on the site. Any trackback that comes in will go into the moderation pool so that they will not be displayed until I either approve them or copy the IP address to my banned list, and delete them. So now I put the trackback file back to its original name, so people can send trackbacks to my site but they will not be displayed until I approve them, and all spam trackbacks will get their IP address banned and the trackback deleted without ever being displayed, so no google benefit for the effort.
