Too bad, he's a terrible beggar - and I wouldn't doubt a scammer... but there has to be reason. All 3 of these posts were made within the last couple of hours - still nothing about him trying to convince people to send him coins via Paypal or whatever as OP claimed. In two of the posts you linked he's asking for a loan. And the other he's asking a question but still relating to receiving not selling coins. At worst - at least right now, he's a troll. Now if I read his previous posts and saw that he's actually targeting noobs, attempting to make deals, then sure. But right now, OP has no leg to say homeboy is a scammer. But I'm no scammer pro - I've called out a few every now and again... but perhaps OP should get someone else to evaluate this.
