Look at the posting history of the comment posters, not just the comment.
In many cases it's not the particular comment, it's the particular poster who is shadow-banned, and all of their comments are dead on arrival (to everyone but themselves, the definition of shadow banned). But people with showdead=true and enough karma can vouch for them to resurrect them if they're worthwhile.
