Funny thing is...there are so many shorts, as you claim, yet this thing keeps climbing!?!? Explain that with some sense. Would LOVE to hear it. If shorts keep piling on, shouldn't this stock go DOWN?!? Why not? There is no logical reason other than fraud.
Bingo. Pain trades abound. HFT algo jam scams that go against all logic. AMZN has gotten away with it forever even after poor quarter after poor quarter. Many sell side analysts in on the scams and the SEC is either complicit or totally clueless.
