I am thinking to remove captcha plugin from my comments form.
It prevents people using non-visual web browsers to comment. And, it is annoying for others (at least I know, I dont like them)
But, this plugin (together with 2 more) is helping me to filter all the spam. I usually have about 100-150 spam comments a day!
Do you have better solution for comment spam?
If it can be easy integrated into serendipity it would be great.
maybe something like that: http://paulgraham.com/spam.html
