The best way to manage the number of social profiles in your library is by hiding anyone who posts irrelevant content to free up space.
How to Hide a Social Profile
Find an asset in your library shared by that Social Profile and click to open the asset’s [...] menu.
Click Hide content from @socialprofile.
We’ll automatically stop detecting that Social Profile’s content forever (or at least until you unhide it). We’ll also automatically delete any detected content, which removes it from your list of Social Profiles and frees up space for someone new.
How do I unhide a Social Profile?
You can unhide the hidden Social Profiles if you decide to see their content again.
Here's how to do it:
Hover over your left tab.
Choose Settings from the list.
Go to your Workspace tab.
Click on Hidden Social Profiles.
You can select all the Social Profiles you want to Unhide from here.
