Most people will not meet, but can understand that to an extent, what gets me is the ones who say they will meet then don't turn up and there are plenty of those.
What would be good is a member rating system, where members who have meet with other members verify the meet, nothing too personal, just things like was the profile accurate of the member, whether the person/persons turn up, etc.
This would then quickly weed out the timewasters and fakes.
