Brokers seriously don't like letting customers short penny stocks. If they let you do it it's because you have a ridiculous margin account (say, $2 per share... or more, heck I don't know I'm not going to try it).
Shorting 100,000 shares of SAPX would require you to sit on at least $200,000 in a margin account and the potential upside for shorting 100k shares is only $3000 (and that's if the price of that 100k shares drops to exactly zero).
