Wikipedia:Articles for deletion/List of most-liked Instagram posts
The question of whether this is  is an interesting one - I'm inclined to say it's not. Looking at articles in :Category:Lists_of_superlatives, they usually seem to follow the same pattern as this one, where the value attributed to each item in the list is sourced, but there's no source for the list/ranking as a whole. e.g. in List of oldest cats, we have a citation saying that Nutmeg lived to be 32 years old, but we don't source the claim that this makes her the 8th oldest cat. Perhaps the reason this pattern has been allowed to stand in so many articles is that identifying and sorting the largest values (of cat ages, Instagram likes, exoplanet sizes, etc.) can be considered a form of |routine calculation? Given the popularity of superlative lists, I do wish the topic were treated
