Is There a Way to Be Silent on Social Media?

There's no way to know that someone is being silent on social media. In a way, it only get louder. The only way to be son it ust not to play or not to be on it. I'm trying think backt like i c chatrooms, you would at least have your name pop up in the use list, but wouldn't be saying anything. But we have no affordances that suggest presente without noise.
