From what I've seen/heard of this rule. The admins do it when they see you as trustworthy enough. I wouldn't go insisting an admin to whitelist you, cuz that I think that can get you blocked.

I dunno, but this is what I heard from another guy where the same question was asked.

Got it, I was just curious.

I searched it up on Safari and apparently you have to have over 300 edits and you had to have voted on at least one proposal. So why aren’t I whitelisted?
