I've been getting a lot of contact form spam. I constantly get "requests" from "different" companies offering to do any combination of web development, seo, etc. I put "different" in quotes, because they're all phrased pretty similarly with the names and company names swapped out. Here's my question: Is there a good way to prevent this from happening? Is there a way we can put re-captcha or some other human verification on the contact form if it's not already? Or if someone could point me in the direction of what template to edit so I can put a message discouraging these folks, should they prove to be humans, that would be awesome.
