I’m with you. But put yourself in the broker’s position. What if GME spikes 300% in half an hour like it already has. Do you want to trust a retard to spot that and exit their position? Do you want to trust your brokerage to detect a spike, make the margin assessment, and close the position in time to not exceed a 100% margin limit? Bet they don’t want to take that risk, so they bump it 300%. Normally this isn’t enough of a concern to bother because you would have to do it for every stock. But with GME’s track record and understanding the $4 per share shorters are still completely f’d and backed against a wall, plus more retards entering to sell options or short it makes total sense.
