Sources can delete published signals by archiving them.
Archiving means that the signal is removed from the shelf, followers will no longer be able to follow, and the source cannot activate or list the signal again, and can only choose to republish a new signal.
Archiving steps:
1. Under the “My Sources” tab, click on the signal strategy you want to archive.
2. Click the red “Save” button on the policy details page.
3. Check the confirmation box in the pop-up window, and then click “Save”.
