In all of reality, most server owners are under 18, meaning the EULA is void, as you cannot form a binding contract with a minor. Furthermore, it would cost Mojang too much in legal costs (attourneys, court fees, traveling) to actually enforce.
More misinformation. Their does not need to be any binding contract, Minecraft can shutdown your server just because they dont like the color of your hair. It is under their power to do that since they own everything you use on your server.
