Should I reply to this Facebook message?

Next time he says "Hello" in a public place, ask him about the message he sent. Be blatant that it is just you being friendly and, if he asks face to face if you want to go for a coffee etc... Then take him up on the offer as a "get to know someone on campus". Make sure you tell as many family and friends of his identity, your intention and, more importantly, his name and his intentions to them. He may be a genuine guy, but whenever anybody you have never personally met privately messages you, be cautious..... But still optimistic.

Be safe, don't be alone with him until you really feel you know him and be open minded. But make sure everything you do initially (if you choose to) is public knowledge amongst friends and family.

You could also ask him to complete a CRB and wait a few months for it to be returned - if he's that interested, he should cover the cost. After all, a true gentleman should lol.

Seriously though. Look after number 1. And certainly don't get really drunk around any male until you feel you know them well enough or you are with a group of friends!
