It will only be a matter of time before sites like Washington Post detect a Brave user and ask for instant transfer of BAT for access.

Although Brave uses Chrome's UA, I think we can ask Brave for it's actual UA - https://github.com/brave/brave-browser/issues/8216

I give WashP as an example because they are extremely anti adblock and most subscribers see ads too. They also have very hard ways to opt out of third party tracking.
