If you don't want your IMGG shares to be available to short then try this. It's from another poster that used off-topic content.
I want IMGG to flourish and can't stand the thought of someone using my shares to short my investment in IMGG.
HOW TO FIGHT SHORT SELLING!!!
"I called TD Ameritrade 1-800-669-3900 and asked the rep to place a Loan Exempt Restriction on my account. Scottrade clients you also can request this. This prevents them from loaning out your shares to short sellers thus helping us longs to help prop up our pps. Please read this link at Investors Hub and it goes into more detail. Bump this up and let us keep this at the top. Spread The Word Brother Longs!!"
"P.S. I hear that some reps are saying that this is not possible; they can't do this for your account. If this happens, ask to speak to their manager. this did not happen to me, but just in case it does."
