Well completing Know Your Customer checks and audits is sort of their job, isn’t it? They provide a service, saying that they will process payments unless the payment is prohibited by government sanctions. But instead of carrying out actual due diligence, they just block anything remotely related and put the onus and cost of doing their own job on their customers. At least they should have a better process to start proper diligence once a customer complains about overreach of their blacklist, to avoid improperly sanctioning innocent businesses.
What if an arms trader used the name “Tickets Limited”? Would they block all payments mentioning tickets? Surely not, as it would hurt their business, clearly illustrating that their conduct is not at all due to “compliance with mandatory laws and nothing we can do about it” but “we did the math and we feel we can screw you over in this case.”
