I'd say... Not supported, why?
People will go all sh*t on this idea. One example is the hair items.
People were like "Make hair, its a great idea"
Some people who supported the hair suggestion was like "Remove the hair, doesn't look like hair at all"

I'm guessing people will complain and be like "what the f? I lost bc of the ghosts! could have had won, you fucking gm's! fuck all of you... etc..." then start a flame fest.
Since No Ghosts Option is competitive, the prize/s must be really frigging high. If the prizes were low, they'd complain and make you remove the option.
Since the prizes might be an expensive item/high tc/ high st, people will start rigging matches, split the money afterwards, etc...
