I have no idea what you're trying to say, but FWIW I never used social networks - at least not the ones you can use to plan events (LinkedIn doesn't count).

Alice and Bob are planning a party, they might invite Anna but don't want Mallory to show up and ruin everything so they turn to Facebook and create a closed group for party planning. Anna, being privacy conscious, doesn't use fb and expects to receive an invite on Signal. But Alice and Bob decide not to invite Anna because they're Danish politicians and Anna is against Chat Control.
