I know, they stick out like a wart. But hang on to them just in case another scam artist shows up and pumps the price. Put in a "reasonable" sell order GOOD TILL CANCELLED and let it sit there. That way if there is a pop you might get out with a "few cents". I know its a long shot but what else can you lose that you haven't already lost?
I had a few million shares in my UBS account and had them removed last year. I wanted to use SSTY as a tax loss. I still have a million + in my Ameritrade account though. I'm regretting now that I had them removed.
