Scammers will try to skirt rules by making sure to adhere to the letter of the law, even if it’s plainly obvious they are violating the intent of the rule in question.
Rule 407b: no real money gambling apps
Scammers: it’s not real money. It’s Linden Dollars. Or our company script. Or our new NFTs. You can’t reject us.
Should the rule have to list out every single thing that could possibly used as currency? Because there are people who will argue that point.
