Here's what the FCC says about requirements for news broadcasting.

In the first clip, it says that hoaxes are a violation. Many of those so-called "false flag" events would qualify for the complaint here. We'd just need to be able to prove that they were hoaxes in some way. This isn't to say that nothing happened, but we've been lied to about key details such as that they may have been staged. If these events diverted law enforcement or public health and safety authorities, it fits the FCC's definition of a public harm, it appears. If the station(s) knew that these events were hoaxes, they could be culpable.
In the second clip, it talks about news distortion as a violation. The statement in the clip says that the FCC generally does not intervene in complaints of news distortion due to First Amendment rights.
"However, as public trustees, broadcast licensees may not intentionally distort the news: the FCC has stated that 'rigging or slanting the news is a most heinous act against the public interest.' The Commission will investigate a station for news distortion if it receives documented evidence of such rigging or slanting, such as testimony or other documentation, from individuals with direct personal knowledge that a licensee or its management engaged in the intentional falsification of the news. Of particular concern would be evidence of the direction to employees from station management to falsify the news."
So there you have it. There's been plenty of information shared on these boards that could provide evidence for both of these. But it appears that it must be those with personal information about the breaches who make the complaints.
