I'm not sure about the first part, my Quest is currently refusing to let me see it on a PC (works fine in link mode, but can't access it's storage in explorer) so I can't test what the dialog does. Although that sounds like I might have clicked "don't show again" in the past and it defaults to deny now. 😞
(The link allow dialog works like that. If you click "don't show again" for that, it defaults to no link until you manually enable in the settings)
For the second question, NerveGear is a post count rank. Below 5 posts is Level 1 - NerveGear (the vr headset in the anime Sword Art Online).
Level 2 is Brain Burst (a game in the anime Accel World).
Level 3 is Hiro Protagonist (the main character in the vr novel Snowcrash).
etc.
For a few people it is replaced with a custom title unrelated to post count like Oculus Staff or Volunteer Moderator.
