Rule 4560 is required for all members, and applies to the OTC as well as the major exchanges.

The rule requires member broker dealers to report. There aren't many broker dealers who will short on the OTC. The vast majority comes from firms that can claim to be large individual investors, not broker dealers. They are not required to report their short interests, but can if they want to. But they don't want to.
