I think this is balanced and fair. I don't think they demonstrated any supremely shitty opinions, i.e. racism, bigotry, but their presence was incredibly annoying and they didn't really participate in useful conversations and moreso used the reply box as a soapbox to say a lot of nonsense.
Moreover, I think banning until the election shows an understanding and restraint by the administration team that is commendable.
I see I wasn't up to date on my Monk lore... I blocked them fairly early on after a weird conversation.
