Well, it's true they don't communicate about bugs with their community much, but I'm pretty sure I've seen them say as much before. If nothing else, Riot Morgageddon told me in a support ticket conversation a while back:
"I'll poke the team myself, but from having worked with them before, the hitboxes are sized and placed properly (though I can understand your confusion, especially as a player who doesnt' have access to behind-the-scenes info)."
I know, it's pretty ridiculous that we need behind-the-scenes info to figure out what's going on.
EDIT: Now that I think about it though, I guess this doesn't really address the fact that the hitboxes functionality is broken too, but then Riot doesn't like to talk about the many bugs that ruin their game. They really like to pretend it's stable, probably for E-Sports sake (even though fixing it would help there).
