No, they are not. I’m in two groups. None of them are in the groups. I only use Signal for Real life friends from my Country. I never joined any random group. These people are from all over the world.
Well in cinemas I’m obviously silent because there are strangers. I just like to talk when watching movies together privatly.
I think its really nice when the movie is a total brainfuck to make theorys with friends. If you just want to sit there in total silence even in private situations you could just watch the movie alone.
