1. Planting moles in target companies — The shorts plant “moles” inside target companies. The moles can be as high as directors or as low as janitors. They steal confidential information, which is fed to the shorts who may feed it to the friendly media. The information may not be true, may be out of context, or the stolen documents may be altered. Things that are supposed to be confidential, like SEC preliminary inquiries, end up as front-page news with the short-friendly media.
2. Frivolous SEC investigations — The shorts “leak” tips to the SEC about “corporate malfeasance” by the target company. The SEC, which can take months processing Freedom of Information Act requests, swoops in as the supposed “confidential inquiry” is leaked to the short media.

   The plethora of corporate rules means the SEC may ultimately find minor transgressions or there may be no findings. Occasionally they do uncover an Enron, but the initial leak can be counted on to drive the stock price down by twenty-five percent. The announcement of no or little findings comes months later, but by then the damage that has been done to the stock price is irreversible. The San Francisco office of the SEC appears to be particularly close to the short community.

3. Interfering with target company's customers, financings, etc. — If the shorts became aware of clients, customers or financings that the target company was working on, they would call and tell lies or otherwise attempt to persuade the customer to abandon the transaction. Allegedly the shorts have gone so far as to bribe public officials to dissuade them from using a company's product.
4. Paid bashers — The shorts will hire paid bashers who “invade” the message boards of the company. The bashers disguise themselves as legitimate investors and try to persuade or panic small investors into selling into the manipulation.

This is not every dirty trick that the shorts use when they are crashing the stock. Almost every victim company experiences most or all of these tactics.
