We identified verified creators as such, but didn't make the non-verified state as explicit. We largely followed a similar pattern to that of Twitter (checkmark for those who are verified, and nothing for those who aren't).
When you visited a YouTube channel, website, etc., we would show you the name and favicon for that resource in the tipping UI. In the case of some YouTube channels, the page name was just the YouTuber's name, and their favicon was a picture of their face.
The changes that Tom Scott and others suggested back in 2018 were ground-breaking. They helped us realize some naïve decisions in the UI/UX of the tipping process and more. We moved quickly to implement those changes (https://brave.com/rewards-update), and the entire system is now substantially better as a result. But there was never any ill-motive involved. We had BAT, and we wanted users to give it to their favorite creators. Tom Scott approved of the changes at the time, which was a nice way to wrap things up
