The BAT that was moving around at that time was from Brave. We allocated hundreds of millions of tokens back in 2017 to a User Growth Pool. We distributed tokens to users of the Brave Browser, and allowed them to send those tokens off to their favorite content creators. This is similar to how PayPal lets you email money to anybody, even if they aren't signed up on PayPal. Our thought here was that users could effectively earmark the BAT they received from us, and that creators could sign up and claim those tokens.
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
