I am ukrainian and use this dating site service. You are wrong saying the women there are all scammers. You must have bumped into such type of women but it doesn't mean to stick this cliche to every woman. You haven't just met the right or compatible person.
I am a doctor by profession and still haven't met my pair neither in Ukraine nor abroad. Generally loneliness is a global problem.
Mostly men are not gentlemen, looking for pervert things online, meeting ladies for one night and are fake. They are weak to care about their new met ladies and marry them or be at least true friends. Many foreign men are heavy alcohol abusers.
So nice people live everywhere just hard to meet them.
