I’ve started to think about turning off commenting. Even with RECAPTCHA, I am getting tons of WordPress comment spam. For example, while I’ve been writing this paragraph, 5 more spam comments came in. For the sake of recording 117 legitimate comments, I’ve had to filter out 7,783 spam comments. A pretty poor signal to noise ratio.
If I decide to turn off commenting, amateur radio operators can find my email address from my call sign using any of the normal means. I may also try activating a second level of spam protection. It’s sad that i has to come to this.
Low SNR for you, but extremely high for the rest of us. Gotta keep the real audience in context. 🙂
Have you looked at Akismet for spam reduction?
