If the comments are [dead] but not [flagged][dead], the account is banned. If a past commenter has been egregious enough, the mods will ban not only the main account but also put in some checks to prevent a user from creating new accounts to otherwise circumvent the ban--comments from such new accounts are also marked [dead]. As others have pointed out, if the comments are worthwhile, they can be vouched. There are differing opinions on this method of banning, but it does allow comments to be vouched for.
