WordPress aspx front end

This may be the wrong place, if so, I apologize in advance.
I created a WordPress entrance handler in c#/aspx which is somewhat similar to the captcha premise using random generation and selection. I created because of continuous spam registrations. I was curious if others think I am wasting my time and should just stick with one of the captcha plugins. My main reason for writing this was because I also needed something that works with WordPress, Drupal and phpBB which this does so far. I was however also curious if anyone else would think it was useful, I am offering it all for free if interested. (requires .net capable site however)
I am testing an example at https://DynaGroups.com if you would like to preview, this is simply a test website I created for this purpose. I have information and downloads on 247Coding.com (which uses the Drupal version) and may also switch that site to WordPress. I have instructional vids on YouTube on use/installation which are on 247Coding.com. WordPress surprisingly was the easiest to get to work because of the plugin capability made it very easy.
Well, just looking for feedback and if it is something anyone would be interested in, feel free to hit me up on gmail using abitowhit or respond here if applicable.
Thanks for your time. So far WordPress has been great to work with and well written! Hats off to all the developers out there.
