If a bank is comprised of 66% of their customers being narcos, the bank gets shut down.

You don’t get to facilitate in illegal shit and hide behind your legitimate customers. Likewise, if you are a customer of theirs and know they heavily transact with illegal services, it’s on you for getting blocked.

Their legitimate customers are. If that means getting the operator to clean up their act, so much the better. If they won't, then at some point their legitimate customers will suffer.

And will probably have to jump to a more expensive provider who isn't subsidizing them with spammer revenue.
