I finally decided to put an end to comment spam – I’ve installed a captcha. Whilst I was away on holiday I received around 3-5 spams a day, so rather than just deleting them I figured I needed to prevent them.
The wordpress docs are a really useful resource. I decided to go with SecureImage since it looked fairly good, and wasn’t complicated to set up. First I installed ImageMagick, then I dropped the php in place. I did have to tweak it a little bit to replace the short PHP tags with the full ones, but then my configuration isn’t standard.
Since doing that I’ve had no spam. I’ve also had no other comments, but hopefully that doesn’t mean I’ve broken my blog 🙂
