I very rarely use emojiis on github. If I can't add anything to the discussion / issue, I post nothing. So if there's enough people like me, an issue can languish.
However the barrier to entry for a lot of issues reporting is pretty tall - requiring triplicate documentation of everything. It's like an overreaction to the sort of people that need to be told to unplug something for 30 seconds to continue the support call.
And that's if they even "allow" issues.
I was posting in issues note frequently 1-3 years ago. I'm sure I'd be sheepish about some posts.
