Sad, a false, fraudulent claim. Please cite your source for the claimed short figure.
In the MMEX-scam case, MM's like CDEL are exempt from this rule - they use short-and-cover tactics, all intra-day, from the infinite pool of MMEX-scam shares created from Mad Jacki-boi's floor-less convertible toxic debt program, including anti-dilution warrant coverage.
Understanding the game is key to avoiding being defrauded - failure to understand the game creates new MMEX-scam bag-holders.
Try harder.
