The best course might be to spread this far and wide with a firm caveat that the evidence is forthcoming. That way when it does come out it is not buried and will be undeniable. Well, except to those who claim that evidence is not evidence. The point is to put such people in the minority.
The other possibility is that, by naming gatekeepers, you cause these people to lose credibility. Ironically, many of these alleged gatekeepers have been making the claim of others as controlled opposition for a while now. Without evidence, you are engaging in "He said, she said." And may be in fact doing what you say the agents are doing by muddying their message.
Blah blah blah.
