This is what Finra does, from the link that you were provided. Finra does not provide, nor can anyone link you to, the list of stuff that Finra can't do:
Created in July 2007 through the consolidation of NASD and the member regulation, enforcement and arbitration functions of the New York Stock Exchange, FINRA is dedicated to investor protection and market integrity through effective and efficient regulation and complementary compliance and technology-based services.
FINRA touches virtually every aspect of the securities business—from registering and educating industry participants to examining securities firms; writing rules; enforcing those rules and the federal securities laws; informing and educating the investing public; providing trade reporting and other industry utilities; and administering the largest dispute resolution forum for investors and registered firms. It also performs market regulation under contract for The NASDAQ Stock Market, the American Stock Exchange, the International Securities Exchange and the Chicago Climate Exchange.

The SEC ruled that, coming out of suspension, brokers could not quote the stock without complying with Rule 15(c)2-11......if you like I can provide the document that shows that. If you like, I can quote from or link you to Rule 15(c)2-11. Finra cannot direct it's members not to comply with that ruling. I'm not sure that I, or anyone else, can provide a source that specifically addresses that issue.
