If this happens to my FirstName+LastName accounts I’ve staked out, I’ll be pissed.
My guess is that they label every account with a lifetime customer value number, and if the costs of your database entry is more than that, they cull it for “being a bot”.
Use the opposite algorithm: cull by lifetime value descending. Gets the bots and the viral celebrities!
(I know it's untenable, but I'd honestly love to see what the equivalent of https://millionshort.com/ for Twitter or YouTube would be like, where the top million contributors and all shares/comments about them were hidden. What would be "hot"? High-value niche-interest stuff?)
