Let me preface this by saying that I am genuinely sorry you went through that - you didn't deserve to be harassed over something like that, and I truly hope you're in a better place and have a support network.
That said, something like that wouldn't fall under hate speech - hate speech is generally going to be on the basis of race, religion, sexual orientation, etc. And as unfair as it may seem, even hate speech is protected to a degree by the First Amendment (I am speaking of American law here - I don't know how it would be handled in other countries) and Section 230 still provides protection to the platform it's posted to (as well as allowing the moderation and removal of said speech without repercussion.) What was originally posted to DR wasn't hate speech - people are allowed to express their opinions or criticism.
