You can see the [dead] comments if you go to your profile and enable "showdead". Most of them are very bad, but from time to time you can find a false positive and vouch it.
Yes, I keep that enabled. I guess I provided poor examples but what I'm saying is that it seems like on Reddit moderation activities are quite obvious (i.e., a giant chain of deleted comments tends to indicate moderation and elicit resentment) and here they're less obvious (there's an air of strong moderation but little to point at directly, which is great IMHO as it evades resentment).
