If this is real, the trader is insane. Annualized returns 106%... MDD 2.97%... Sharpe Ratio 8.95.....from 2016 to 2021.....
There are thousands of funds around the world, at any given time one of them will produce spectacular results with an extremely small drawdown, nothing magical or extraordinary about that, it happens every day.
I wouldn't rule that out either (small account after all so anything goes), but I am not familiar to what extent you can game Fundseeder.
In general, if you are the webmaster/owner of a website you can publish (or not publish, meaning censor...) anything you like, don't you think? And, in doing so, you can create any illusion you like, or sell any idea you want.
Jack Schwager wouldn't put his reputation at risk by promoting and faking a small $180K account. He does write about excellent traders in his books so it actually would be strange if those excellent traders didn't exist. If any trader wants to show such great results to anyone, it would be Jack and his FundSeeder. And they import data from live Interactive Brokers accounts, so it's not easy to game.
Consistent and profitable traders do exist, I am not denying that, far from it. And yes, I really enjoyed Jack Schwager's books, every serious trader should read them.
