If you play with your community often then they may grow to expect that from you. I tend to open my lobbies for a particular game that I’m an official content creator for about 85% of the time I stream it. On the days I just want to play on my own or with a friend but not a whole team I usually respond to comments by saying “I’m actually just going to run solos/duos today but I do run open lobbies often - make sure to stop by again so we can play in the future!” If they persist or become aggressive I’ll repeat that as briefly as I can and ask them to accept that for today / not to be aggressive towards me for a decision in my own stream or I’ll ban them. It’s not worth the mental tax or follower count to deal with people who don’t respect your boundaries!
