Yes. Currently, there are wide areas purposely disruptive posters can target. Only big offenses earn a ban, and it's easy to avoid going that far. Minor offenses are overlooked if they happen only once or twice and earn all of a "please stop" PM if repeated. As continuing to cause trouble in minor ways just results in further PMs, there's not great incentive given to change behavior.

Three (or four or five or...) strikes and you're out might work in those situations, but if that's not formalized, it's just an arbitrary decision on the moderator's part. It seems far better to establish infractions through open discussion now, update them based on experience and feedback as time goes on, and use them to try to curb deliberate, repeated disruption of the forums. Infractions add something of a ticket option in between the sometimes insufficient "let off with a warning" and the undesirable "revoke license".
