High walls! The discussion

[PNWMan]

this may be a bit of work, but here is a plan I propose: request users to either remove their plot walls or move to the very edge of the world. If the edge is filled, then kindly suggest that the owner of the plot to move (or if they haven't been on in months and likely will never join again, move it anyways). And, for a definition, I think "high" is about 32 blocks off the ground.
