You've actually raised a fantastic real example of this in practice. If I post a trollish comment, it'll likely get downvoted and/or flagged/hidden. In plausibly accidental cases, someone might leave a comment saying "you're likely getting downvoted because <douchey thing>." If I demonstrate a significant pattern of the same, I'll get shadowbanned (or fully banned). You don't need to behead drivers of annoying bikes, but chastisement, mild punishment, and then significant punishment, is a sensible escalation. One potential system might be where the first offense gets a warning to fix the problem, the second offense gets a ticket and order to fix the problem, and the third gets the vehicle impounded.
