Rules still apply in the derailment thread. If you don’t like a member of the community mute them.
Here is a link for TS rules and in this case specifically pay attention to this one:
1.) Above all, be civil. Be respectful of the topics and the people discussing them, even if you disagree. Do not attack, name call, bully, belittle, gang up on, badger or harass other community members
If you see something you believe is against community guidelines or rules flag it. Lets look to help, not fight.
