So I told you guys a while ago that, because Minecraft's "Open to LAN" feature listens on *every* interface and address, some friends and I can use it over a tunneled VPN.
Doing this, we've also discovered that, if the host did not turn on cheats for the single player world they're sharing, **they do not have access to admin commands necessary to kick and ban users**.
Because some people use DmZ or otherwise don't have a NAT, at any given time, there's probably a few dozen on these on the public internet. They're inherently ephemeral, so you likely won't find them on shodan.
