Also since you're stupid I'll point out that if you try to play a non-point farm setup as a red heart, you'll be drowned out by point farm setups before it fills.
Just lock it, so no cheaters / trowers join after half the round has passed. Competiton is for competition, not for leasure. They are golden hearts on purpose. If everyone wants to play serious, they can on red hearts. The difference between gold and red is that gold are for competition.
Just lock the god damn round, from trolls to join.
If someone wants to join the competition, they can join the next round, like everyone else. That way the new 2 vio - you are out rule, will actually be usefull. Because people will just use alts to throw again.
