Buy sell depth and fake sells

I have watched AZY closely for the last couple of days.

The sell queue is approx 8m and the buy around 28.2 million. This afternoon there was a 'fake' sell of 5m at the back of the .48 cents queue that vanished as soon as one the the sells in front of it were hit. There was a similar 'fake' sell for 1m at the back of the .49 queue but it appears to have been scared off by the movement at .48 cents.

The above buys/sells have been apparent for the last 3 days at least. Could it be someone or something trying to keep on a lid on the share price?

I think AZY is like a compressed coil and ready to jump up.
