no database, nothing to hack. The other thing that puzzles me is they have a pledge of not passing any details to any one else, so apart from sending the site users news letters etc which we can opt out of and as far as I know most do, why do they need this info.
I know some of them cheat. By adding an altered letter in the sign up and seeing if it appears in spam. It has, a telephone company said they needed my mobile number in case we were cut of testing my landline shortly after that, I started getting spam texts and calls. I vigorously complained to the phone company about this as apart from two friends and my wife who had my number it must be them. it didn't surprise me the calls and texts slowly stopped.
