One of my sites that uses the gravity forms contact form plugin has suddenly started getting hit with a lot of contact form spam. The form is completed properly, but with a fake email address and the message is some variant of "call me quickly, or call me, I'd prefer to discuss over the phone." Googling the numbers show that they belong to escorts. Is this some BH method for affiliate earnings with escort agencies, deliver a caller and get paid? Or is some one simply trying to jerk me around with spam? Or something else, I haven't thought of? I have a developer license with gravity so was I going to ask them to take a look at this. I've used gravity because, in my experience, it is much better than any of the other contact forms at blocking bot spam.
