This is what was being sold on r/conspiracy very heavily a few weeks ago. There were multiple posts with upvotes in the thousands (which I did not believe were organic).

EDIT 5 minutes later: I go to r/conspiracy_commons, and sure enough there's a post with a novella-sized tweet from the guy flogging it, Ashton Forbes:

My name is Ashton Forbes and I am currently disclosing the most important videos in the history of the world.

The videos in question are that of the true fate of Malaysian Airlines Flight 370, on March 7th, 2014 at 18:40UTC at the Nicobar Islands.

So this is round two of the campaign. I'm surprised to see Kim Dotcom joining in. Or maybe they really are the most important videos in the history of the world.
