Agree. If you think a stock is overvaluated then must have posibility to short it. Markets are fighting with money. Modern wars. Its ok to make alianses. If cant accept fighting between Bears and Bulls then stay away from trading. If you are confident that social network community is pushing price high with irrational motives or too risky agenda then wait for right time and go short. Will have enermous profits if you are right and price will crash. Why to blame anybody? Its normal market situation. Manipulation is normal. Be smart and calm. Observe market and trade it accordingly.
