Market makers are just that - they take instructions from those who want to buy and sell. A short squeeze occurs when those that need to cover as cheaply as possible compete with those who realize the potential of a stock and who have made a decision to buy up to a particular price level because they don't want to be left out.

The reality is, despite perceived "walls" of around 300K on the ask on occasion at every level from .0105 upwards over the last 7 weeks, they have been taken out day by day. Also, today, despite a shenanigan where 450K were sold for no reason as low as .0106 / .011, it took one second and only 356K in buys to get back up from .0106 > .0153.
