You can wonder and crack your head over it, but what's the harm in answering someone who isn't who they say they is??? You will never know. It's they same thing when you give money to a begger, you don't know what he's going to do with it, but that's not your problem. Don't be too cynical of people... be careful with personal details on the net, that's about all you can do.

If one person is revealed as a fake, then you will start searching for the next one etc and you will lose trust on this site...
