Posted a small fix to WordVerify today. If are using WordVerify and have noticed that trackbacks and pingbacks suddenly stopped working, well, join the club.
Turns out the comment routine that WordVerify hooks into in WordPress is the same as used for trackbacks and pingbacks, so those were getting killed. I added an exclusion there so only actual comments require verification.
Update: Gah. And with that I promptly got 3 trackback spam.
