Teleport glitch

If you've ever played in a moderate sized server (10-24 players), you may have noticed that you've been teleported to where Humans spawn where they previously joined, and not to where you were earlier, that is the Teleport Glitch.

This is in no doubt, always annoying and never beneficial. Even when trapped in blocks is a better situation then being spawned to where the creepers spawn, which is the hillside.
