It'd say it's more of a general idea that, if a user is being banned for the same offenses each subsequent ban (even if it's the same severity/degree of offense) that ban will become longer each ban to help deter repeat offenders. And once they reach a point where they've been banned dozens of times for the same/similar offenses they will get a really long ban. Or, ya'know, something akin to that.
