WordPress Hashcash

WordPress Hashcash 2.2 – Elliott Back

Comment SPAM is a terrible blight on the blogging world (blogsphere), but WP-Hashcash totally eliminates comment SPAM.

A simple challenge is presented to a visitor’s browser using JavaScript (which most SPAM bots won’t be smart enough to have). Once the browser computes the hash correctly the comment is accepted otherwise the comment is denied.

I thought this was a far better idea than forcing users to type out letters in an image; which always seemed like a bit of a pain to me.

If you run WordPress, then go grab this plugin; it’s all in one file, unlike some other plugins which disperse themselves over several files.
