>But imagine if someone built purpose-built software for causing traffic jams, and a large community of regular users make traffic jams 5 times more common than they used to be.
What's the difference between that and someone who simply drives bad/slow? Do they get a pass because it doesn't have "purpose-built software"? Or is it because they're not acting as a group? If cheaters are not acting in a coordinated way, do they get a free pass as well?
