Shorts on a pink sheet stock too risky IMO

pink sheets can run 100%+ day without any fundamentals or news NO seriou short seller would take that risk EVER! 
Short seller do excellent DD and uncover many frauds etc

dont get me wrong in the pinks there is and always will be PLENTY of manipulation and I believe we witness that with ticker FUNN but when volume pours in that stops too.... 

with MM CSTI gone 5s are up
