this could not be more clearly a scam. he even posted "Lulz"
come on now
It can really sound as scam, but I've to say that Ninja/Hollie orderd me 2 laser engraved cards and I still waiting for the money
, Stefanie also ordered 1 and payed quickly; the postal postal address is in Texas, while Ninja seems to live in Australia. Not that a 0,5BTC transaction is a big proof but it can be only a coincidence
