@evan The challenge with this is that it can also be used by bad actors. Let us assume that we roll out the feature you have requested.
I am a bad actor spreading disinformation. You reply with a link to the corrected information. I delete your reply therefore ensuring that nobody who follows me can have their bubble pierced.
Better yet, I can reply to you and then Block some relevant replies. Leaving only enough to make you look like a bad actor.
And there's not a good audit trail for this.
