From the contents of the ftp server given as a reward I believe the person doing the puzzles is Tandin Wangdi.
If Tandin Wangdi is the guy, he'll bail and there will be no further puzzles, because further puzzles would confirm to us it's him.
If the puzzles continue rule him out.
I've found a link between Raven and Water issues in the Bhutan region.
Raven is an author cited in research into Bhutan rivers and dumping vehicle wash.
Raven, P. (2013). Virtual issue:Freshwater ecology- Understanding ecosystems and reducing
anthropogenic environmental stress. Journal of Applied Ecology
Oh hey didn't think anyone would actually come.
Nope no IDs here cause everyone's on Tor. Also you have to manually type in the post you're replying to to link to it, like >>3122.
Post raven stuff in here. See you Dec 17th.
