(Updated with further detail on the fake SEC suit.)NEW YORK ( TheStreet) -- A controversial short-seller who has made a career out of accusing Chinese companies of fraud was the victim of a hoax on Tuesday. According to a document that rippled across the Internet, the Securities and Exchange Commission filed a civil suit against Carson Block, the short-seller who composes critical reports on Chinese companies under the name Muddy Waters, alleging stock manipulation. The document, however, was a fake. SEC spokesman John Nester confirmed as much Tuesday morning. "We've issued no such release," he said. He declined to comment further.
