Call to order! Call to order!

We require a new name and definition for a certain breed of vine commenter. I call to your attention those commenters that come in to your article or seed long after the conversation has died. Those commenter who drop several boisterous comments, on articles and seeds that have already been argued or discussed to death. Yet they leave comments challenging other commenters to respond or to rebut their premise. So it actually looks like they have won the argument, even though people have stopped tracking that article weeks ago. I have been noticing these individuals for quite some time now, because I never stop tracking an article or seed. If you were to go back and take a look at your older articles or seeds, you would see  the post of a group of individuals who are having discussions with nobody, but themselves. Typically you will see a string of posts challenging a comment or premise and then ridiculing the lack of response. It becomes pretty obvious, when the date is several days behind the last comment and the ridiculing responses are only seconds, or minutes different in time.

So, I submit to you, the members of the vine, what name shall we call this new type of commenter? What should be the new definition to be accompanied by the new name?
