Tossing who in a blanket?

Given the recent policy change stating that IMDb sometimes DOES remove valid data, what guarantees can IMDb give me that in five years time, this title is still listed as it is currently listed: https://www.imdb.com/title/tt0227672/reference?

(Obviously, this is not a question about just this specific title. The question can also be read as: (Why) Should we keep bothering spending part of our free time updating the database?*)



*If I'm not mistaken, all the information regarding admission numbers has been deleted because of the software change about 1,5 years ago, but it's still gone and I know of no reason to expect these to return shortly.
