I am lucky to say I just witnessed other people in restraints - I only have been in seclusion twice (the longest was 7 days) - and they made it hell for me - to stop me from doing what I did again which did not work... It just traumatized me and shut me up - I will never go back to that place voluntarily ever again or seek help. And no, I could not do anything about that, since I was sectioned.
