The best thing to do is to document your own tree well, including making notations in the text for events if explanations are simple or including writing a research note as a "story" to explain the evidence and your conclusions for what you have in your tree.

What and who other people put in their trees is up to them. You can alert them to a problem, but if they do not correct it, it is their problem and not yours, as long as you have documented yours well.
