Please delete and block the keyword 'special'

Currently, 155 titles (most of which are tv-specials) have the keyword Special attached to them (https://www.imdb.com/search/title/?keywords=special). To me, this seems to be a useless keyword as it's extremely ambiguous. Does it mean a tv-special? If so, there's already another keyword (tv-special) for that and shouldn't be listed. Does it mean the title is so good/different/experimental that it's special? If so, opinions shouldn't be listed as keywords and for experimental films, there's already the keyword 'experimental-film' (https://www.imdb.com/search/title/?keywords=experimental-film) because IMDb doesn't give truly experimental films (like for instance Andy Warhol's Sleep: https://www.imdb.com/title/tt0187513/reference/) their own genre designation. Or does it mean that one of the characters is considered 'special', either because the character has a certain disorder or quality? Can a staffer delete all occurrences of this keyword and then block it so it can't be added again?
