KDE Plasma is great!
Feel free to keep on trucking with your setup. I’ve been using a different solution for discord streaming and wanted to share in case it sounds helpful for you. It’s been an improvement for me. Your mileage may vary.

Do not use your main account, make another one only for streaming with audio. Works with x11 and Wayland has more features. It’s a slight annoyance to have to connect to a discord chat with a second account but this works really well for streaming. TOS is sustained with main account and you actually get working audio/video streaming with a second account that won’t get banned (been doing this for years) but even if it does it won’t matter because it’s only used for streaming.
Just another option, feel free to disregard if it’s not right for you.
Memmy on iOS has filtering under settings. Haven’t tried it yet but presumably typing in “hexbear” would not only filter out comments/posts from the instance, but also comments/posts about it from other places. Never have to deal with any of the drama again. Also filter out anything else you don’t want to see.
