Are we talking about the opt-in ads (which might contain "Cryptocurrency span") or the affiliate codes (which are injected into pages you've already decided to visit)?
Brave is truly capitalist cancer in browser form. I thought we killed off IE & Netscape. Turns out they had a kid.
Edit: Forgot to mention, they stopped injecting the links 2 years ago as they claim it was a mistake (maybe, maybe not, but for sure not the case right now) -> https://brave.com/referral-codes-in-suggested-sites/.
Like in the sibling comments that confuse it with cryptography-crypto :D
