That’s nothing. I’ve heard of people getting the cops called on them because the cashier forgot to scan an item and they noticed after getting home and went back to pay for it.
Sponsorblock does not harm creators. Youtube has no method of detecting when a sponsored segment is skipped, so the creator still gets their sponsorship money. A person who is using sponsorblock is extremely unlikely to use the sponsored products even if they did watch the ad, so the creator isn’t losing out on any affiliate money either.
