I’m now using SpamKarma to regulate the torrent of comment spam flooding this site. Most people (I hope) won’t notice anything different, but the fact that I no longer have to manually delete comments bearing cialis or Texas Hold’Em poker site ads is a nice comfort. 🙂
If somehow you do manage to trip the spam detector, you’ll still be able to validate the entry using a Captcha. For visually impaired users, authentication through e-mail is also possible.
It’s in testing now, so please drop a line if anyone experiences difficulty with it.
