@Lafu, it seems to me that you and @nakamura12  are not friends, collaborators on any project, or that you may belong to the same local board - so I wonder where this user got the idea to contact you and ask for $5? To me, such a move is strange to say the least - I mean in the sense that you're asking $5 from a complete stranger, right?

I think it's good that you opened this topic, because if nothing else, maybe some people will realize that they shouldn't ask for such things via PM.
