Contact Form Spam

Someone, or some sort of bot, has managed to spam our contact form. I've received HUNDREDS of form submissions from two different forms in the last few hours. I have blocked the IP address but they are still continuing, I am assuming on some sort of auto send. 

I have also closed the two pages that those forms are on until I can get this sorted out. Any advice or help?

I have had to close my site until I can figure this out. I don't know how long it takes to block ip addresses, but I'm up to over 14K page views today....the majority of which are from 2pm to now. Does anyone have any idea of what might be happening?

You should contact your host about blocking that IP address.

You can also block it in a .htaccess file.
