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 
My favorite thing is when they accuse hexbear of downvote brigading. I've seen it a couple times.
LOL
I like when they accuse us of calling them specific insults, and then I can't tell what ones because it's blocked by the filter.
Someone in one of the federation threads posted a screenshot of their comments with negative karma as proof that they were downvoted for comments on Hexbear.
No bro, you could only have downvotes from other federated users, guess your take was that trash.
I honestly forgot the fediverse has downvotes.
