One more thing could happen: the editor could see all the duplicates, and thinking "what a sleazoid spammer" delete ALL of them ... or try to delete (n-1) copies and accidentally delete all (n). The former case is allowed for in the guidelines, although it's not that common; the latter might be considered editor error, and in my experience is not all that common (less than 1% of all rudely repetitiously submitted sites), but it does happen (
). It is stupid, though, to set yourself up so as to make it easy for someone else to harm you via an understandable error.
Our approach to repeatedly submitted sites will be colored by the fact that most of them (but not all of them) are spam from the first -- guidelines-violating marketing/doorway sites with nothing that we would see as unique content. And, it matters not how profoundly mammalian your ancestry is -- to dress yourself in feathers and waddle and quack your way around your local swamp during duck hunding season is a very imprudent course of action.
