Willing to do Friends&Family paypal option so no risk of chargeback to you if you are a trusted member here.
Wrong. Family/friends option can be charged back. Simply dispute the payment by advising PayPal it wasn't you or it was a fraudulent payment and you know nothing about it. PayPal has reversed such payments and will not hesitate to reverse yours if brazenly challenge the transfer after getting the coins.
As for references and feedback earned elsewhere, trusted traders here usually rely on the internal trust system of this site. It may not be a solid indicator of integrity but it is a definitive measure of one's credibility.
Be careful of requests to chat on Skype. It is a scammer's preferred choice of communicating with their victims. Private and zero interference from those sharp eyed members here who might ruin their scam strategy.
