They sometimes do questionable things. Someone I know had an offshore corporate account verified to level4, only for them to give notice of account closure with 72 hours to move funds away from exchange, NOT allowing to withdraw fiat. As a result the company was forced to rebuy crypto they sold, at substantially higher price, thus resulting in a huge loss from the action of kraken. This is not considerate, and giving 72 hours only to move and restricting fiat when the exchange rate is unfavorable is an a*****e move.
