The error of the ways of Coinbase seems to be allowing various transactions and money transfer activity, sometimes for lengths of time, on unverified accounts. Then, suddenly boom, there's a problem, and customer support is already backlogged.
Kind of like they opened the door to unlimited new subscribers and sobbed that they were overloaded. With some of the HN crowd playing the violin music of poor, fast-growing start-up (the "growing pains" cop out).
Naughty (greedy) Coinbase.
