Thanks to Mike Sprague for pointing this one out: CFFormProtect. This is a great resource for the CF programmer who is creating public pages that are prone to spam attacks, such as Blogs with comment forms. Wondering what exactly CFFormProtect is all about?
CFFormProtect is a fully accessible, invisible to users form protection system to stop spam bots, and even human spammers. CFFormProtect works like some email spam protection systems, in that it uses a series of tests to find out if a form submission is from a spammer or not. Each test is given an amount of points, and each test that is failed accumulates points. Once a form submission passes the threshold of ’spamminess’, the message is flagged as spam and is not posted. The points assigned to each test and the failure limit are configurable by you the developer.
Version 1.0 of this valuable script was released the other day (01/30/2007). You can get more info about it on Jake’s blog.
