In the Coppermine photo album on one of my websites I suddenly got a lot of comment spam. The causes are obvious. I’m allowing non-registered users to post comments on popular web photo album software.
Coppermine is a great photo album. Unfortunately the scum of the world sends their spam to the most often used packages like Coppermine. I also started receiving spam on a Coppermine installation on one of my websites. I found a good solution in the Captcha plugin, prepared for Coppermin by Abbas Ali. After installing this, the user needs to type the letters he can read, but a bot can’t. Here’s howto.
