If you have a Guest account your profile is not and won't be public, visible and accessible to any user of the website but Hosts.
Only Hosts can visit and see your Account but just when/if you book one of their Dance Spaces and/or send them a message.
If you see other public Accounts on Dancerents it's because those are Hosts Accounts, which are always public.
If your account doesn't look like theirs it's because your account is a Guest Account. You can have a profile like Hosts have just if you publish at least one Dance Space on the website. After that, your Account will be automatically transformed into a Host Account and it will become visible to all website's users.
If you have a Host account your profile should have more features and menu items than Guest Accounts (e.g. "Listings", "Calendar", "Bookings", etc).
