Most are scams. There are some legitimate ones...but few and far between. It just takes common sense. Why would an 18 year old who looks like a model want to leave her family and friends to go live with a balding 40 year old, in a foreign country with a language she can't speak? Also, Russian life isn't that bad. They have everything North Americans have except a smaller house and no car (I have talked to a few Russians).
