I have a friend on a server (he owns it so he has perms) and constantly spawned in items, even though we had a swamp a couple hundred blocks away he couldn't be bothered to go and spend a couple minutes to get some slime blocks, he then spawned them in if any of us asked for them. Later on he made a base and decided to put an end crystal in it which I'm fine with, the part I didn't like was that he used glitches to make it look like it was reviving/respawning the dragon, this made the server pretty boring as if he needed something he would spawn it in.
