I would tag covered_eyescovering_eyes instead. I think censor stuff is technique/effect done by real world to prevent viewing some parts while covering/covered is the act of the characters.
Doing some brief searching, the colloquial term for lobe-stretching objects seems to be "gauges" and has already been added to the tag gauge on some skrillex posts: id:1759299,1759300,1759305 etc.
