There is a glitch to survive forever on pretty much every map. The little kids who think sitting in these glitches for days and getting them to the top of the cheater boards makes them cool.

Every time I try to go to a public survival game I see someone doing some Halo rocket jump thing to get out of the map or go to the safe room.

I just wish they would fix this... Here's a clue, TAKE OUT THE GRENADE LAUNCHER.

But against all of this they can modify the boards or use God mode mods, etc.
*sigh*
