I think that if an outright war is raging in the comments, let it run it’s course. All parties are willing participants, free to disengage at any moment.
The exceptions should be when illegal content is being shared or illegal activity is occurring (CP, doxxing, etc).
It’s always frustrating when a juicy argument gets locked because it’s “unproductive”. I was having a great time watching it unfold, both sides hurling both creative and uncreative insults, oblivious to how low they are sinking to. It’s great!
Why are you on a discussion forum for insults? Just go on 4chan or the comment section of YouTube. Or play a RTS with voice chat on. You will hear all the insults you want.
