Most singles who have tried meeting people from online dating sites have come across this telltale internet dating scam sign: being asked to either cash someone's check or money order for them, or being asked outright for money. The story varies somewhat with each internet dating scam, but the intention remains the same: robbing you of your hard earned cash.
If somebody asks you to wire them cash online - no matter what the reason, no matter how plausible or sad it sounds - don't. But if you feel compelled to do it anyway, at least read FraudAid's legal responsibility page, first. It details the ramifications you may face should you choose this route, no matter where you or the internet dating scam artist lives.
