It got so bad over the past few days that I was regularly deleting 5+ posts a day advertising the latest gamling establishment or where to get the cheapest erectile medications. So as with all good reasons for doing some programming - being pissed off - I wrote some captcha code that will display an image of some text that you have to enter to authorise the post.

The image/captcha is not there if you create an account, so please do so.

Oh, and for those interested, I coded it from scratch without outside 3rd party code and merged it into my existing 3rd party punbb forum code.  Total time, approx 1 hour.
