While everyone has the ability to search for your profile, only Paying Members can see content you’ve set as “Paying Members Only.” Content you’ve set as “Visible to everyone” can be seen by, well, everyone!
To change your visibility settings, choose content to post, then tap "Who can watch" and select either "Paying Members" or "Everyone."
From here, you can also choose if you want to allow non-members to pay to view locked content by tipping you in Sunbeams to unlock the post.
Tip: Members that already have a membership for you don't have to tip to view posts on your feed.
