Wow! At 90 GH/s that one address accounts for more than half the entire pool size. That's an operation, not just some guy.
According to searches, I think this is the Chinese whale. I guess he grew up, because last I paid attention to him his farm was a lot smaller.

Used to be, when you clicked the Search for User button, you got a list of wallet addresses, and how much hash per day they were generating, and how much payout they were getting. I did spreadsheet to see where I stood in the mix. And I took down the address of the guy who had been top dog for a few days running. I set alerts for his address on blockchain.com, so I get email about how much he is taking in. I named the alert "CMFish"...
