I recently noticed my view were falling drastically. I worked hard to create new pins and even promote a few to help however the views kept falling. I knew something was wrong then I learned about shadow banning and it seems if someone does not already follow me they cannot see my pins, search my pins, my account, and I cannot follow any new account.
Pinterest is a waste of time now, don't mind those who say create a new pin here because it won't do anything.
