The problem might be with your service. Do you force users to sign up before you share any details with them?
I routinely provide fake info when a website that I think MIGHT be something I am interested in, but refuses to give me enough info to know for sure, until I give them a bunch of personal info. NO THANKS!
Sometimes I tell them my name is Bob. I live at 123 Main St. My email is bob@nowhere.com. If that works to get me in the door, then I can look around to see if I want to become a real customer.
