The tradition of journalists using anonymous sources doesn’t mean they use anonymous sources, it means that they know who the source is, considers them reliable, but agrees not to name them. Usually they require multiple independent sources.

Unknown sources on the internet are usually not reliable. Anonymous sources should not be trusted, even when there are more than one saying the same thing. Bots and deliberate misinformation abound.

This is not a hill you should die on as it’s a hill that can greatly harm democratic society.
