At current prices, the figures you quote indicate less than $300 short, at the ask. Not exactly the stuff a "short squeeze" is made out of. On top of that, the current amount traded would indicate plenty of liquidity at levels well below where margin calls would start.
Perhaps you should look into how a "short squeeze" really works.
Less than a million shares being actually shorted does not result in a "Squeeze", one miilion shares currently is $200. Not exactly going to cause a whole lot of panic over a $100 loss if the Ask raises to .0004 as the short position will dump to the Bid for .0003 at that point.
