Facebook has so many people so serious over who is blocked and private and everything.
This cannot be good for anyone.
My daughter was upset for 3 days because someone blocked her!
She did end up making a fake account under a different email address and get back in to see the other persons account.
Not that it made a difference,
but it set her mind at ease in some crazy dimension.
So to answer your question;
if you open a new account under a new email you will be able to see them.
And if you just go into the original account and change the PW it will still block you because it is the same profile.
