D&D 5E Mordenkainens starting to show up in the wild?

[Demetrios1453]

Already seen one guy claim to have the book on Reddit, just a matter of time before somebody feels like sharing.

Just saw that too, although Australia instead of North America. Granted, he didn't give any real info, other than Asmodeus and Lolth aren't given stat blocks, which would be a reasonable guess whether one had the book or not, so I'm not too sure on his story until he gives us something more substantive...
