Codeberg is run by people. People who can make contextual judgments. They're even pretty explicit about it in their blogpost; that it's not going to be a search-and-destroy process, and that they're generally communicative.
In that situation, anyone who is complaining that the rules are "too vague" is probably just trying to figure out exactly how close they can get to violating the rules without getting kicked, and that's precisely the kind of people who would not be welcome on a community service like Codeberg. If you actually follow the spirit and intention of the rule, it would never even get to a point of ambiguity.
