Three-strikes-style rules like this make for easy decision-making, but they don’t make for good decision-making. They eliminate curiosity about the root problem, reject the reality of how humans learn (it is almost never linear), and usually end up backfiring catastrophically at some point. Compliance by fear does not make for open and healthy communities.

The fundamental attribution error makes us believe the problem must be that this kind of person is “not interested in listening to reason”, but I can tell you that the ones who aren’t interested in listening make that abundantly clear when you ask them to stop. They are not the ones I struggle with. The problem cases are those who act in good faith but have trouble regulating their emotions, infrequently enough to not be an obvious menace, but consistently enough that I recognise their names.
