Janny makes them.
I've had it done to one of my A&N shitposts before for posting satire but, as I predicted in that thread, everyone forgot about it in a week and we all just went back to ragebaiting with impunity.
Edit: found the thread in question. Text body is mine but title was edited by a janny (free of charge, of course).
I guess the premise relies on the targets being MATI enough that they keep coming back to their containment thread to argue out of a compulsion to have the last word.
