"no need" to get into hearsay, deep character analysis, pleas to please not target this person for harassment since I am being so extensive in my criticism of this person, etc, e.g. what I just wrote above, it should be clear, trust your facts to speak for themselves a little more than you are giving them credit
Based on my reading of many related sorts of threads like this, the problem with trusting the facts to speak for themselves is that people don't read the facts before responding ... as you can see even from this thread.
In practice you do need to provide interpretation of the larger context, otherwise someone else will do it.
Also, if you don't make a plea to not target a person, then you'll be accused of trying to incite others to target that person.
Your terms "hearsay and rumor" appear deliberately chosen to color the more generic phrase "anonymous" or "third-party". As such, I cannot answer your question as I disagree with the characterization.
