I operate an adult comic book publisher and Coinbase shutdown our account without notice and blamed the bank they work with (despite the fact that we were not converting our BTC to USD). All support tickets took 3 - 5 weeks to get a reply and it was always unhelpful.

For a company like ours the whole appeal of Bitcoin is the anonymity, so our readers don't have to worry about buying lewd comics and having it show up on their statements. Coinbase tarnishes what Bitcoin stands for and they do not protect artists/publishers.

Do not use Coinbase.
