Security problem with WP 2.1

These are likely not comments, but trackbacks.

Install Bad Behavior and Akismet. These both block spam in different ways, and the combination of the two is mighty.

I receive emails about comments, not about trackbacks.
Here’s email content I receive from the WP blog:

Actually, you receive emails about both. Trackbacks look just like comments, for the most part. They just come in through a different door.

Exactly what Otto said – if you’re set to receive emails about new comments, you will also receive them on trackbacks. (I get them all the time.) Te email notification to you is the same either way.

Definitely get yourself some Bad Behavior – it’s a nice little plugin that plays well with Akismet.
