They suspended my account, tried for days to get an answer why, claimed I may be using the funds to fund terrorists. I accept Bitcoin on my website and demanded I turn over all my customer details, not just the ones that used Bitcoin. When I refused they closed my account.
Also every time I sent an email to there customer service I would suddenly get porn spam. I know it's coming from them, I only used that email address for Coinbase communications.
I suspect they only wanted my customer database so they can try to get people to move over to them.
