okay, wow, um..................... this is really weird, because first of all HOW IN THE WORLD DID THEY EVEN FIND THE MAP?!?!? if it was private then they couldnt have found it unless someone leaked out the link to a bunch of people, and if you know that everyone in youre group wouldnt do that then if someone has a grudge on you then that may be the reason that those italian people are in youre map, either that, or the people that invaded youre map did some hacking to find a new map if they were bored of theyre old ones and wanted a new map to explore, and then they saw the creator of the map and lied to make it think that they didnt hack and just found the download as if it was a public map. thats my best guess why theyre there.
