If I remember correctly, it's against RMS ruling that servers pay to get reviewed or content creators. Correct me if I'm wrong, I'm going to the best of my knowledge here. Lost my old account as the old email for it got pruned.
Here's a post from their announcement on Discord:

I see there is no mention of RMS review? They paying streamer should not have anything to do with RMS listing?
