It's interesting to see the shift because I've noticed the majority of male players are new (made their accounts in 2020). I feel like the female players tend to be more loyal to the forum over the years whereas male users just jump on the bandwagon and would leave once they become slightly disinterested in the game.
New Horizons definitely brought a fkcton of casual male players into the pool who wouldn't have picked up the game without the hype, whereas female players usually grew up with the game since childhood days
