Brigading absolutely happens in SRD. We can talk about whether this style of content should exist, but it does not "exist with the explicit purpose of brigading other subs."

Right, it exists with the tacit purpose of brigading other subs. But like Kiwifarms, blurbs in the site rules mean nothing given the context of the community.

The original post was very clear about the word "explicit." That's what I'm commenting on here.
