The ones I met made sure not to surpass a certain rating ceiling. They were significantly strong players, but they pretended to be weaker. They also share their Lichess accounts with players of different strength, including lower rated players.
People get creative when it comes to making some money. I'm not saying it has to happen here though.
Well, so much money it isn´t unfortunately at these Hive levels. And to deceipt your rating over 10 weeks seems like a lot of effort.
But in principle everything is possible.
