PHP Temporarily Banning An IP
<p>I'm creating a contact form for my company and I want to make it as spam-proof as possible. I've created a honey pot + session checking, but I also want to make it so that it's only possible to submit the form once every x minutes. In other words, banning the IP from using the form for x amount of time.</p>

<p>What is the best solution to do this?</p>

<p>I can think of a few but none of them seem ideal.</p>
