Is there a single word for "not allowed to be released?" [closed]

Is there a single word for something that is there but not yet released because it has not been allowed to be released? I am an artist interested in words having to do with the blocking, stifling of a person due to oppression, violence and or fear. The oppression, violence and fear can also be internal due to learned behavior in an environment filled with these things.

A word often used in this context is suppressed:

foreign correspondent's copy is not censored, but certain news is suppressed

the incipient uprising had been completely suppressed

This can also be applied to internal thoughts or processes:

disciplined to suppress his personal impulses.

it has been hard to suppress the question.

the satisfaction of a suppressed creative wish [T.S. Eliot]

Censored is the term that comes to mind reading your question:

• suppressed or subject to censorship. *The censored press in some countries.

The Free Dictionary

From Wikipedia:

Censorship is the suppression of free speech, public communication or other information which may be considered objectionable, harmful, sensitive, politically incorrect or inconvenient as determined by governments, media outlets, authorities or other groups or institutions.
