It is a shame they allow their MM's to borrow retail shares to the point they are in a short squeeze position. Possibly what is going on with IHGP and Scottrade. Though they won't ever admit that. Never has eTrade restricted a stock. They use different MM's or create their own market with their own MM when others won't take a trade. TDAmeritrade's MM's are notorious for shorting the heck out of stocks also, then won;t allow TDA retail customers to buy at the bottom.
Just means a short squeeze opportunity very likely with the right movement and buying pressure for IHGP.
