I had to look up astroturfing in this context, so hopefully I got this right. But isn’t that just the actual commenting then? Obviously voting could get that comment moved closer to the top when done by the perps in this case but I think it would take the community to also be up voting the comment for it to rise to the top. I also don’t think knowing who commented actually fixes this issue nor does it give more ability from an admin perspective to get rid of those comments if that was desired.

I could be missing something though.

What is the benefit here in this case? Basically why do we care who upvotes or downvotes something that it needs to be exposed?
