I thought of a self moderated thread but I think it could be seen as a biased channel and would not help with the actual problem.
I wanted to bring the topic here since it is very easy for moderators to see that the aggressive behavior I commented is specific to the group of users I included before and goes against basic civilized discussion.
Still appreciate the suggestion, but would love to solve it without creating a self moderated thread though

The things that you mentioned - insults, aggressive behavior, etc - are not moderated. You can report the users for actual rule violations, such as multi-posting and low-value posts, but you are also
multi-posting yourself so I would suggest to
read the rules first.
