This is a pretty big what if statement, but technically, internet laws, apply to what country you are currently in, if your country doesnt have a law against hacking, your safe, so 'if' you were in, say, antarctica, you had a generator for power, and some kind of Wifi, you could hack sombody without anyone being able to take legal action.
Anyways, even if you put a 10 hour game cap, on a new player, so he couldnt earn pp so fast, and capped sombody to 1 pp earning trade a day, they could 'still' get thousands of pp easily, as 'again' this 'would not' stop a player with high ammounts of money, perlan as example, from trading a mill tria for mabey a mushroom, giving the new player thousands of pp. its immpossible to prevent somthing like that, without sombody complaing and complaining non-stop.
Becuase if this 'were' implemented, people would become familier with it, and demand that the limits be loosened, whreas eventually they just might be.
