If you build it, the spamming pieces of shit will come.

I’m speaking, of course, about forms. I’ve written in the past about my attempts to build a bot proof and spam resistant form. I use the two terms independently because they are two very different things. Even if you block bots, you’ve not necessarily stopped the humans that post to test the forms as well as posting actual spam. If you’ve built the form correctly, it’s actually impossible to completely block spam. A human posting spam is indistinguishable from a human using your form for legitimate purposes. Well, aside from the fact that they’re stupid. And evil.
I digress. Let’s get to the form bits. In my past posts, I’ve spoken about broad concepts that have worked for me. This time, I’m going to provide the actual code I’m using. With my latest change of checking for a valid MX record, I’ve completely stopped spam on the form that I’m using this on for over a month.
