Leaks and Evidence

With so much BS and fakes being posted nowadays, how or where would be the best place to submit actual evidence (anonymously) if you had it?

Places like 4chan and reddit would probably not be a good idea. Maybe give it to a news network or someone “trusted” in the UFO community?

Using a throwaway account on Instagram/Twitter/Facebook would be pointless because almost nobody would see it.

I don’t think it would be a good idea to give to a government official and hope they do the right thing.
