If you have found your profile on Hive without ever signing up, this explains why.
What the directory is
Hive publishes public pages listing creators by platform, topic and country, for example top photography creators in a particular country. They exist so brands looking for creators in a category can find people who fit.
Why you are on it
These listings are built from information that is already public on your social media profile. Your handle, your public follower count, your profile photo and your bio. Nothing private, nothing from a private account, and nothing you would not see by visiting your profile while logged out.
You do not need a Hive account to appear, and being listed does not create one.
What being listed does and does not mean
It does mean brands browsing that category can find you.
It does not mean you have an account, that anyone has your contact details, or that you have agreed to anything.
If something is wrong, or you want off
Both are straightforward. See Correcting or removing your profile information.
