lol cope and be normal I guess? I understand insta isn’t great with privacy but it’s a group chat for your room mates. Make a burner account instead of forcing all of them to download some app they’ve never heard of for one group chat with people they are forced to be acquaintances with.
They’re likely all thinking you’re the odd man out because you’re making a fuss over a group chat.
Yeah I’ve never seen insta used for group chats, but it is a commonly used app so I see their reasoning of “let’s just use the app that almost all of us already have set up”
