PayPal has a similar problem. They do really loose string matching on the OFAC list[1], for any data, in any payment field...even a comment. Match a magic string in a comment, and your PayPal account gets locked down in a way that's very hard to undo.
Yeah this was a big thing back in the heyday of CSGO skin trading. Putting the word "damascus" into a transaction comment would get your account locked.
