does X share some kind of list of who is earning what on X? 

I'm genuinely curious on their payout process, how it's similar/different to Farcaster, and why X wouldn't payout in stablecoins here.

X has not publicly disclosed detailed earnings data or a specific list of who earns what. Their payout process is somewhat opaque, differing from platforms like Farcaster that offer more transparency. X's decision not to payout in stablecoins could be due to their focus on native token X, aiming to build and maintain the ecosystem around it.
