Got an apparent request from someone through this service, but have no means to sign up for them without a phone number and miscellaneous other information they have no business getting. I find that highly suspicious - it's not explained what they need it for. Not going to risk dealing with this site any more than necessary. Normally I would add "I don't even recognise the name of the person", but I can actually think of several legitimate reasons someone I don't know by their real name would contact me if they landed in jail. (They're not *likely* reasons, but I can't just brush it off entirely.)
