You can't effectively short low/sub penny stock which make up 99% of the stocks here. If it was possible you would see high short interests in all the blatant penny scams, but there never is due to the reason I stated. So no, personally I never take any position in stocks I criticize.
All the shorters/evil naked shorts blah, blah on low/sub penny stock message boards is nothing but lying promoters, ill informed noobs and sometimes long term tin foil hat bat crap crazy pennny stock losers.
