yeah, if you wanna donate and it is one way to put it, the real world still do the same, so i see no cheating in here.
but if you are using some token software to add-in the token than it is serious issue for those who buy tokens with hard earn money.
for me, i don't spend any real money into it. I like to be under dog and wanna win against big team.
I disagree with you O.P. people can spend money which ever way they want as long as the money never over your own limit.
