not all brokers are doing this. scottrade in particular wont even allow any buying on it, they say its been deemed not liquid enough......not enough volume for what its worth. even though when i asked why they thought that they had no reason. they allow trades on other companies with little to zero volume and massive floats......sounds awfully suspicious if you ask me. and yet another reason im moving my accounts off of a broker like that. heard the same about ameritrade, but i cannot confirm it 100%
