Oh. They take a 5% cut. Next question, how do I prevent this system from working on any of my websites?
You could refuse to serve to web browsers with a Brave user-agent. Or I could fetch your website using wget and strip out ads. If you can't control a user agent in other situations, why do you want to control it here?
Looking into this further, they would eventually email me after there are $10 worth of funds queued up for me, and then after 30 days of me ignoring them, those funds would be spread out amongst other sites who do want them.
However, until that wallet has at least $10 in it, Brave is just sitting on top of free money. I don't want that.
[edit] P.S, Brave doesn't identify it's self in the user agent header. I just downloaded the Linux version and it identified it's self thus:
