How large is your online friend group?
2-5 people: very cute, will be fine. Have fun! Easier to communicate and settle small disputes
6-10 people: still cute! Can get rocky, maybe not close with all of them but its fine. If you don't like someone you can just ignore them.
11-15 people: its more like youre friends with a handful of these people and just know their friends. You don't want to dislike them because your friends might dislike you? Rough territory.
15+ people: you know a handful and just tolerate the rest. I advise against following the crowd blindly, be aware of clique like mentality. If you find yourself ganging up against others cut off most of them as they're promoting toxic behavior. Just be aware of yourself and your ideals and don't give into peer pressure.
