@Riot, Why Do You Ignore Some of the Highest Rated Community Threads on the Story and Art Boards?

In particular, why do you ignore these threads regarding the lore of Runeterra?

Despite being rated highly important threads by players, these threads have yet to have any kind of red response after weeks/months of being upvoted by the playerbase:

Seriously, these are threads that are highly upvoted by the community, and are actually asking significant questions about the direction that League of Legends is going in. For some reason, Riot won't respond to any of these threads, despite the upvotes.

Seriously, I thought these new boards were about threads that were important to the playerbase getting more attention.

Riot, could these threads get some responses from you guys? They're pretty important to us.
