I think this is THE ULITMATE mistakes of mistakes that anyone in their right mind could ever make.
Because one thing--no matter how good your camera is on your screen is--it will never compensate for when you actually meet that person and sit with them.
Plus, you never know a person really until you 1. Travel with them 2. Make a business transaction with them 3. Live with them.
So I just would say NO NO NO don't do it. For women--it's dangerous. For men--it is risky because you really really do not know this person-there family, their values, the way they smell, the way they walk, the way they act and carry themselves--in general . I'd say don't do it. You don't know who this person has been with, or done, unless you ask reliable references...and even in Jordan those are not easy to come by. So --I'd say don't even go that route. You could really get burned.
