Put yourself in the shoes of those reading this RP to decide how it should be treated. Nicole Hayes, from what I found, was a captain of LN. Now, different factions use different ranking systems. If we use the old LN account, a captain is one step away from admiralship but is still a mid-chain officer in charge of basically navigating a single large ship. If we compare it to ground force, it should be a colonel. Not too low for sure, but not high enough to know the real deal of secrets and all across of a house. The suggestion of @"Czechmate" here is valid: officers of this rank usually work on one single project. A char being a navy officer and not a researcher, a captain probably should ensure the security of a facility/project in space. For security reasons, chains usually do not know much about each other exactly to prevent leaks, so I wouldn't expect a captain to have enough knowledge on so much stuff all around Sirius.
Now put yourself in the shoes of, say, my char, the head of Kusari parliament. Let's say KNF or KOI bring this report. In matters of national security, which it is, the reliability of sources is no less important than the contents. What do we see when we look at the source? A renegade captain with personal beef with Liberty who, obviously, wants to portray it in a bad light. Not the first one, not the last. The rank of the source, as explained above, should prevent (if we follow common logic) obtaining any real sensitive info of that scale. So we have a vigilante with personal motives of painting Liberty in a bad light, with very superficial observations, and lack of access to get the said information (in theory). Would it be classified by KuGov as a credible source? Probably, no. Hence the benefits of doing shady RP and trying to get anything out of this "credible" source in exchange for protection in Kusari is more detrimental than suffering worsened relations with Liberty over a renegade whistleblower of dubious importance/credibility with no information of substance. Hence, KOI has pledged to capture her if she shows up and hand her over to Liberty. I think some other factions thought in the same way. It is not we are beating the RP, as you put it, we are playing along its RP depth -> designate it as some conspiracy theory of a nutjob. If, however, there had been a detailed profile of one single project/case (e.g. Willard Station) it would have looked much more credible for other factions to pick up.
