1. Sent Bitcoins to a mysterious man in Brazil who's only reachable by a chatbox on his website, that no longer works.
False, He's reachable by email, support tickets and skype.
I haven't checked his skype out, but I have gotten in contact with him via tickets.
Yesterday i had a problem trying to cancel an order .. and i sent a ticket to the support and it is true was a bit slow, but a few hours already solved and they closed ticket .. So I have no doubt that they are still working and to improve the site and raise the reward in a short time... And Crybabies ever that keep saying that it is a scam that continue crying please. Warn if the handkerchief are finished you

If you feel the need to resort to personal insults then you lost the argument. It is a way of saying that you have no counter without actually saying it.
