Have you ever followed citations before? In my experience, they don't support what is being citated, saying the opposite or not even related. It's probably only 60%-ish that actually cite something relevant.
Well yes, but just because that’s bad doesn’t mean this isn’t far worse.
I follow them a lot. I’ve also had cases where they don’t support the paper.
This doesn’t make it okay. Bad human writer and reviewer practices are also bad.
