I’ve been a bit bothered by various spams I’ve receive these last few weeks on my blog so I finally decided to do something.
Usually, you’ll see people using CAPTCHA plugins that requires you to type some letters/numbers or perform a simple operation. While this isn’t so annoying, I wanted to test something that doesn’t require any user interaction and found this fine plugin (Hashcash) which is based on some javascript magic. I’ve been using it for the past two weeks and it worked fine so far (I don’t have comments, but I have no spam either, so that’s fine with me).
