I’m unfamiliar with this ‘suicide game’ concept, but anyone encouraging troubled people to off themselves should be keelhauled. Literally keelhauled. Find and old ship with lots of barnacles.
I agree with hetero. If they happen to survive finish them off on a cross. Takes 3 days to die that way usually - slowly drowning in your own internal fluid build up.
Not to punish these scum. I leave it to God to judge. But to discourage the next human virus that thinks encouraging girls to kill themselves is amusing.
