All Bitlinks are permanent and can never be redirected or deleted.
If you'd like to remove a link from 'Your Bitlinks' list, you can archive the link. Archiving means you will no longer find the Bitlink in the 'Your Bitlinks' view or via search. To archive a Bitlink, click on blue, circular archive icon once the desired Bitlink is selected under 'Your Bitlinks'.
To view all your archived Bitlinks, click on 'Filter' at the top of your Bitlinks list (located next to the search bar) in 'Your Bitlinks'. From there, you can select ‘Only Archived’ and view all the Bitlinks you’ve archived. See one that you’d like to unarchive? Hover over the blue, circular 'unarchive' icon and click into it! It will appear in 'Your Bitlinks' view on the date you first saved it and become searchable again.
