Like I said elsewhere: these kinds of schemes don't really "work". The best that happens is you get away with it for a while until you accidentally do it to someone with resources.
Are you carefully vetting every single entity whose content you show this pop-up on (regardless of what description you choose to use to spin what it is) to make sure none of them have trademarks that could be enforced against you? Because if any of them do, game over. You can hem and haw and deflect and pretend to be helping creators as much as you like, but you don't have the legal right to appropriate someone else's mark to raise money.
And if you are vetting to make sure you don't pop up on anyone who has a trademark, what if that comes out in discovery when someone goes after you, and suddenly you get to answer questions about whether Brave knew that what they were doing might not be legal (as evidenced by the care they took around trademarks), did it anyway, and now it's really over.
And like I said elsewhere: when the shit hits the fan, what's your personal plan for Brave deciding that all your "helpful" comments here weren't authorized and were in fact misrepresenting them, which led to the terrible misunderstandings that provoked the legal action?
I'm trying my best to help you see the ways this can go badly. I'm also very sincere in my advice of "lawyer up". I'm not your attorney and this isn't legal advice, but I think you should have both an attorney and legal advice.
The folks who've run this scheme in the past were mostly small-time, and the worst that happened was they were forced to stop or retool because they weren't worth the effort of going after properly. Brave has attracted enough attention and money to be a lucrative target for someone to eventually turn into a smoking hole in the ground. Please, for your sake, fix this or get out of it ASAP.
