Are you banning stirfish and bavent as well, who recently engaged with this account? It seems to me like most of their comments are low quality and trying to pick a fight with the person you just banned.
This parent comment (that you just replied to and banned the account for) felt somewhat useful. It is drawing a parallel to a prior SCOTUS nomination (Kavanaugh) and the unproven allegations that came out at a politically opportune moment to generate outrage. His point was that unethical political warfare invites a tit for tat back and forth that spirals into something worse.
