So the spam I've been getting through my site has been getting bad. It got bad when my site was hit with some email injection attacks, after I put in several safeguards against that and other spam, the spam has started to seep through again.

So now I've implemented a CAPTCHA on the registration and contact pages. I've never really done any sort of CAPTCHA before but I was pleasantly surprised it wasn't too hard to get one up and running. Granted these days, from what I hear the spammers are starting to get better at getting past them but I figured every little bit helps.

And there is quite a bit of material on the web for implementing image CAPTCHAs with PHP if you need to use one on a site.
