Most of us don't exist in major online forums. We have numerous online forums and chatrooms that we exist in. Why do you think there's so many based people on twitter. It's because they follow individuals, and twitter can't ban you from following someone. Why do you think there's so many people in secret groups on Discord and Facebook? It's because you can have closed groups that outsiders cannot see. There's one guy on a discord server that I game with. After getting to know me better, he sent me an invite to his private server. Turns out, it's about ten dudes who post racist and antisemitic memes. Most of us don't have a major online presence. Most of us have little to no online presence. And some of us have a little online presence in several minor areas.
