If you turn on 'showdead' in your profile you can see all killed comments. (This is in the FAQ: https://news.ycombinator.com/newsfaq.html.)

There's only one level of removal beyond that ("[deleted]") but we never do that as moderators. "[deleted]" always means either that the author deleted the post themselves or asked us to do it for them.

Thanks. I have it on but I had the window open for a while and went into the profile of one which then longer had any comments so I guess they removed it themselves.
