not on my machine.

EDIT: just to be even more clear, the game is marked as Verified for Steam Deck. i don’t think catching a ban for playing with Proton would allow said game to be Verified. i play on desktop (Fedora 40) and my Steam Deck.

FreeTube uses their own API (Local API) on top of Invidious’ API. you can choose whichever, and the other will be the fallback that’s used.

good luck

i think you would want to start with:

if header :matches "from" "somedomain" { discard; }

but i am just spitballing.

EDIT: i think there is a "reject" as well.
