I'l say it again. Just call Ameritrade. Easy peasy. 1800-369-6900
I DID call Ameritrade, both TDA and TOS, and BOTH of them said NO, there is NO restriction on GGRI.
What cracks me up is that not only is it fraudulent and immoral to spread a lie like this in order to short the stock, but it's also just plain stupid to be thinking about shorting a stock like this at this point in time.
Go GGRI.
Happy 4th of July all.
America rules.
