They either made the story up based on what they read on reddit or you are making it up now based on what you have read on reddit. There is a third possibility that that person being incredibly dumb and they actually believed what they read - but I give that a slim chance.
Why would someone lie about that? Having 30 bank accounts does not confer any prestige upon you. There are companies that do this for people (https://en.wikipedia.org/wiki/Certificate_of_Deposit_Account...) and if you Google "FDIC sweep" or "insured cash sweep" there are a bunch of banks talking about how they support automatically moving money out when an account gets more than $250000 in it.
What's more likely being lost in translation is that they have an insured cash sweep account and explained how that works, and who exactly is creating the 30 bank accounts is what's being misunderstood in this game of telephone.
