If someone is going to scam you, they are going to do it - and if it takes sending a copy of a passport to an escrow to get more ready to scam customers - the cost of a fake passport needs to be priced into the scam!
When did the bitcoin community pick up all these naive idiots who think that rules can't be broken?
the Romans used to say "Caveat emptor" - Let the buyer beware - nothing much has changed in 2000 years!
Every rule can be broken, true... but you can make it more difficult. In fact you were stupid to put money in Stackcoin as it was clearly a scam from the beginning, so i didn't lose any money. In fact i'm not buying any pre-mine coin. I only mine coins NO PRE-MINE, NO IPO, as this means that the coin owner need to mine himself with his hardware to earn money, he need to use his electricity to earn money, and he will not waste his own electricity.
