It’s different for everyone, but for me, it’s similar to the 1 minute section like you mentioned. I integrate it within my video. Not sure if this is what you’re referring to, but if someone doesn’t disclaim that something was sent to them or paid to say it. Highly illegal.
Reason I say Patreon is a lot more work is because usually you need to build an incentive with Patreon as well (community, BTS, extra content).
