I imagined flicking a spinner (inspired by the surprising success of Aella's poll: https://twitter.com/Aella_Girl/status/1594144435000213505?lang=en)

streisand effect

I just picked the 18th digit of pi after the decimal point. 18 was chosen kind of randomly. This turned out to be 8.

Just an idea, you could warn people against reading the comments first, and add a bunch of blank lines to the description to make it harder to absent-mindedly scroll past.

I wonder if due to the very specific community represented here, 7 will be massively underpicked

@ArielKwiatkowski this is my expectation as well

@PseudonymousBosche24f I predict the opposite, everyone knows 7 is the most random number :P
