Several site I frequent have reported a deluge of comment spam within the past couple weeks. Until today, I thought the only recourse was for them to turn off the “anonymous” option. I learned from Orac’s site today that this isn’t the case.

Blogger now has a word-recognition feature that blog owners can switch on to require posters to enter letters into a field before the post is accepted. It’s not a perfect solution, and it requires more work for each comment, but if it kills the spam, it’s likely worth it!
