I agree. Holding my money for 180 days with no appeals process amounts to a tort, and should be considered unconscionable and unenforceable when it appears in a contract. They shouldn't even be allowed to ask for that, because once one player creates such a policy, the rest will follow.
Thought experiment: why not make it 5 years, instead of just 180 days? If a 5-year term were to become "standard industry practice," to paraphrase Dan, who could argue otherwise?
They simply should not be able to exercise that kind of arbitrary power, at least not without being subject to standard banking regulations that can be modified as needed to balance the interests of financial institutions and their customers.
