Some of the most searched numbers are surprising. Why are 8487798767697884826576, 119104105114108, or even 3551 so high up the list? See most searched here: https://numberresearch.xyz/info
All of us use the same keyboards more or less, maybe us randomly typing a large number is not as random as we would like to think. Just like how “asdf”, “xcyb” are common strings because these keys are together, there has to be some pattern here as well.
That means there is less entropy than purely random strings, not that this specific number would be so far outside the distribution. My money would be on someone hammering it.
