I received some spam comments recently, and while I was pleased to see that the spambot account has been deleted, now that it's gone, I can't delete the comments. The comment content is gone, but there's still a notation that username spambot left one. It's not a big thing, but it's annoying - one of the posts was a happy birthday post for someone special, and seeing an empty comment from a crossed-off username doesn't set well.

Will these go away on their own, or can IJ fix things so they can be deleted by the journal owner after the spambot is gone?
