Hey,
This is how it goes for me.
Minerware- Only seen one cheater which makes sense since the gamemode is really just minigames and having kill aura and flying or what not can only help you in a few.
Survival games- I've seen some hackers, but I think the bigger problem there is that so many people team in that game mode since they matchmake with a friend.
Skywars- Here is where I encounter the most hackers more frequently, which does make sense since they can fly and not be knocked off and having kill aura basically guarantees them a win unless if they're that bad even with cheating.
Eggwars- Decent amount of cheaters, but not as many as skywars.
