That's all true. I especially like your last paragraph about the smaller accounts borrowing prestige from the big accounts.

But it seems to me that the amount of effort required to run an account does not scale with the number of followers. Sleeper accounts are essentially free, of course, but an account with 10^7 followers is not 1000 times harder to run than an account with 10^4 followers. Unless they have a lot more people devoted to the smaller accounts, they probably don't have 1000 times as many accounts with 10^4 followers.
