From my observations, they have limited the access to ThanksGG qualification in the begginning of the year - it is harder to qualify now. The sum of the reward stayed the same (100K), so in general it should not have a big impact for regular players.
I have read on rededit some speculations, that it was limited because some people abused it sitting at the same table with friends and producing easy accesible points (it usually was enough to win/loose the 4$ stack on 9max, no matter what cards).
GG does not notify about changes nor exact conditions of getting chips for this flipout by the rule. This is GG help quotation:
"#ThanksGG - How do I get invited to the #ThanksGG Flipout tournament?
Players will be added to the tournament based on qualification by winning with a big pot (GGCheers) or losing a big pot with a cooler (GGCare).
The specific details vary game by game and are often changed based on numerous outside factors. As such, the exact conditions that trigger these events will not be specifically enumerated, Our team of game experts will continuously look for unlucky situations throughout gameplay and will add more trigger points."
From the other hand - it was almost 15K in today's flipout, perhaps it has changed again? We will see soon.
As for chinesse bots - if anyone meet such ones, please let us know - I would like to play against them

(but I seriously doubt they exist on GG)
