Addendum to this (thanks @flippac !): the receipts a victim of harassment could show won't help stop anything, it's all sock puppet accounts. The most information they can share is "see look, this *happens*. It happened to *me*."

Which, let's be honest, isn't that useful in the white supremacist patriarchal world we live in. A few new people will learn to believe the victims of harassment. That's not much return on investment when the cost is needing more therapy.
