This must be the week for spammers.  I had some issues on another site this week.  So I started to tighten up my security on this site.  Of course I found one post with 1300 spam trackbacks.  So I did a bit of reading and found the following article.  It appears several people are just turning trackbacks off all together.  I must say I’m seriously considering it.
