It can be a good idea if King server creates a special room/server for " Server Hacks Fun" only, where players could donate and get features/abilities enabled.
For example:
Donate $5 : Get the high jump feature enabled
Donate $5: Get the flying in flames feature enabled
Donate $5: Get the see through wall feature enabled
To get a new ability enabled, you need to donate another $5.
Important: Players can have this abilities enabled ONLY in that special server/map.
I'm sure a lot of people would love to use those special abilities, for curiosity or for fun.
