The 10% cut is a bit rough but I know other platforms also take a cut, but I’m not too sure if 10% is high or low.
I have a Patreon and their cut is about 3% there (at least for me, it varies depending on what services you use through Patreon). This is a very easy pass and the only people I see utilizing it are creators like Twitch streamers who already have a large Discord server/presence to build off of. It's a bad deal though 10% is real rough imo.
