Comment Spam

Any­one else notice a flood (well, trickle) of com­ment spams? They are com­ments of the form “great site”, “glad I found this site” etc, i.e., all mind­less com­ments that could apply to any site, with senders that are poker or online gambling sites. Some­how they’re get­ting past Spam Karma 2 (which nor­mally catches all the spam), so I’m hav­ing to delete them by hand. It’s not as it I have a par­tic­u­larly pop­u­lar site either!
