The Hobo Method
So this method is where you become a hobo, setup your place near spawn. Have a donation board with a textscreen behind you, with a 1st, 2nd, and 3rd place.
After you have the textscreen setup, start adverting 'Donate to me at spawn, if you donate the most you will get 1st place Donator on the board behind me! A couple adverts later, come up with a random name and say he get you a few million dollars. Now start adverting, 'Billy gave me 2 million and has achieved 1st place on that donation list at spawn, nobody will beat that!' Sooner or Later, players flaunting their cash will come by and donate just for the sake of being above others and being first.
