Its pretty simple - XMR is effectively a single-exchange coin, and on that exchange there is a constant floating buywall way-bigger than any small XMR investors can touch, being moved up and down, with the whales who own it talking about it in the trollbox - the proof is the whale's words themselves Kazuke! 
I'm not convinced, you have to proof in one line, besides we all know the buy walls magically appear and no human being is behind them if so they are tampering with mother nature
That's all the proof I have, and your right, it's not conclusive, Warz could be lying and it's somebody else, I can't prove that...just sharing the info, if you don't agree I respect that, and no need for me to post it again.
