Transposition vs substitution; I'd say F*CK is more likely to suffer the ASA’s wrath than FCUK. But who knows, need more details to be sure of anything.
You would say transposition vs substitution but there a few different string metrics. I picked one of the most popular which treats substitution as the same as transposition.
It shouldn't be hard to argue and force them to disclose what string metric they are using and what distance is the minimum if you're prepared to take them to court.
