  (c) has a very obvious voice. Every time he gets expelled, he tries, incompetently, to disguise himself but within a few days it's obvious who it is. 
  
  (b) is a former Dominican novice or something like that; he knows what he's talking about, his ideas are coherent, he sincerely believes what he says and he's always civil, occasionally a bit grouchy maybe. (c) is clearly not up to snuff in the basics, his posts are all over the place, and he makes errors in basic grammar and diction. 
  
  (b) quotes Ludwig Ott's textbook. (c) quotes soapy easy-reader devotional manuals.
  
  (b) shows up late at night EST, which is morning GMT. (c) posts all day and if nobody takes his bait within an hour or so he posts something even more outrageous. (b) is here to defend the Catholic faith. (c) just wants attention. 
  
  I don't know who (a) is. He could even be a team. His style is less distinctive that the other two.
