Sometimes there is only one word or phrase that can describe a person or a situation.
In the instance that you have outlined, the word you used appears to be totally appropriate.
I experienced a similar censorship issue when I innocently used the name of the small fishing village that lies just north of Bureika in a post on this site.
With regards to politicians, head and brick wall come to mind.
