You can tell on them without telling on them.

 Unless your abuser or aggressor or assailant is dangerous (which means you need to warn certain people or types or groups he might be after), then you don't need to publicly name your abusers or alleged abusers or suspected abusers to find your true people who will support you. You do absolutely need to put out there, in some direct or indirect form, what happened to you and what you went through to find your people and so they can find you since you're their people too. You have the same nature from the same experiences caused by your nature and the same experiences from the same internal nature caused by your experiences.

But no need to publicly shame others who might be innocent of what you are accusing them of.

Saying "You know who it is, no need to name names" is just as bad as naming the name. Worse, because at this point you are just trying to use technicalities to save yourself. You won't have to save yourself from anything to do with this if you just find another outlet.
