"I recognize that piece of bedrock. See you soon."

There is already long established technique to find location on the map based on screenshot containing piece of natural land forms or bedrock (immovable blocks below the terrain).

This has application on large maps where players try to distance themselves from other players to be able to build undisturbed or stream without getting stream-killed.

In particular, it is know that some players got killed mid-stream based on screenshots on natural terrain.
