With due respect, I think that promoting yourself as a "credit union" - which is a very specific type of
regulated deposit-taking institution owned by members - is absolutely nuts when you're in contact with the SEC. They may well be after bigger fish, but that doesn't mean they won't be sharing any information they gather with other financial regulators. Given the questions you say you were asked, it would be better to lend as a private individual at the moment and not style yourself as any kind of regulated business.
Our principal purpose in requesting information from you is to determine whether there have been violations of the statutes and rules the Commission enforces. However, information provided by members of the public is routinely used by the Commission and other authorities to conduct investigative, enforcement, licensing, and disciplinary proceedings, and to fulfill other statutory responsibilities.
