And we shouldn't allow this concept to go unchallenged here on Lemmy.
Commenting on an active post is not brigading
Posting a link to something is not brigading
Commenting on something you were linked to is not brigading
The only thing that might be brigading, but isn't because it isn't a real thing, is someone explicitly going, "Hey everyone, go here and harass this person"
It's all fine and good that we have some new rules to keep the peace with other instances but we must fight against 
I don't think that's true, what I saw was you can post stuff from other instances, you just can't link directly to them.
I would love it if all federated lemmy content was banned from the dunk tank, because then I'd feel more comfortable blocking it again. Like I know myself and I'm going to have to constantly hold in the urge to go in and be contrarian, that comm just really brings that out in me. Probably I should just block it anyway. I just can't really defend this place if I don't know what shit-stirring people have been up to.
