I understand your point, but from a creator's perspective the bigger issue is visibility and engagement.
I have a verified livestreamer account, two clubs (public and private), a group, and over the past few years I've noticed a significant drop in reach. Sometimes it feels like my followers don't even receive notifications when I go live or post updates.
I've posted messages in my groups and clubs that received almost no reactions, which makes me wonder how much of my audience is actually seeing my content.
So my question isn't whether private clubs should exist. My question is whether creators will actually have better communication with their members inside private clubs, or if they'll face the same visibility issues we already experience elsewhere on the platform.
