Okay, So I know that xray is totally forbidden... However, what about in the rare occasion with chunk errors, in where the textures in a chunk fail to render.. Is it against the rules to look around below? I mean it would be kinda hard to use a chunk error to ones advantage because of not knowing the distances and they are pretty rare as it is..
I can't see how they are possibly illegal. They happen to me all the time, especially when I teleport in town, I assume because the game moves faster than the communication with the server. The event is much rarer for me in the wilderness, but it does happen on occasion.
