Reg SHO reporting (which you can access daily at http://regsho.finra.org/regsho-Index.html) reports naked short sales. MMs have 13 trading days to cover these shorts.
Short interest reporting that you see here http://www.otcmarkets.com/pink/quote...=fasc#getQuote (forgive the plug) is FINRA requiring firms to report short interest positions in all customer and proprietary accounts in NASDAQ, NYSE, NYSE Amex, NYSE Arca and OTC equity securities—as well as other listed securities not reported to another self-regulatory organization—twice a month. I've read this information includes naked shorts.
