Dustin Moskovitz, co-founder of social networking site, Facebook, is still dumping shares of the company. Moskovitz disclosed on August 24 that he had sold 900,000 shares of the social network over six business days following the "lockup" of stock that was awarded to him during the IPO.

He is continuing to dump shares, and has gotten rid of another 450,000 shares at a rate of 150,000 per day from Monday to Wednesday of this week, according to filings with the Securities and Exchange Commission (SEC).

Even though Moskovitz has dumped over one million shares in Facebook, he still owns more than 130 million shares in the company.
