I don't give one shit about the welfare of porn makers but I don't think this should be allowed. A law should require the bank dig up and cite individual on-ledger events for their decision, and also have to provide a documentation demonstrating a valid reason for the inevitable gaps between all those events and the actual depersonizing. Valid reasons should be highly limited and humiliating or scandalous (like "we can prove that our company has been behind by x range of time in fulfilling all security functions at this level of priority") so that in order to cancel a person or class of person flippantly they have to expose themselves to healthy risk.
