I joined a small server with a friend. I promised to be a "Vanilla" server (and it was). There were no command blocks or anything, just some rules under a barrier block at spawn. The entire spawn protected area was in a swamp biome, in the water. My friend swam across and started to chop down a tree. A Admin who was just finishing building a bedrock wall (in creative mode) flew over and told him, "No floating trees" before he could break the third block. He immediately gets killed by the admin (who doesn't realize that anyone can see that he has Sharpness 100 Unbreaking 100 or that the owner could probably tell) and banned. I was about to quit when he banned me along with about five other innocent people. I seriously hope that he was not the server owner, as that was a wonderful idea for getting people to join your server.
If the admins will ban if they get killed, why do they even play their own minigames in the first place?
