businesses cannot lock out a customer from their funds, or cause undue stress or delay but they refuse certain services to customers that do not wish to comply to their policies. EG having the withdraw/deposit fiat buttons disabled unless KYC details are verified.
I think what you meant to say is "businesses SHOULD not lock out a customer"... because obviously they can, and there is nothing anyone can do about it. I know one case where MtGox's locking a man out of his account is causing severe stress... He is an older man, US citizen, has 7 stents (valves in heart), living off-the-grid in south America for 7 years, and was paying his healthcare, rent, buying food with bitcoins. Now he has no money, and therefore no access to rent, healthcare or food. But MtGox stands my their "you need to validate yourself", and has so far, not accepted the documentation he has sent in (because he has no permanent address or apostille sealed document less than 6 months old)
If you stand by your "cannot" statement, then, when MtGox's policies actually DO lock someone out, who does one call to remedy this (I mean besides MtGox, who does nothing).? Is there any kind of oversight group that monitors/regulates these exchanges? Becaus the way it is now, the client is the last voice to be heard.
