oh boy, you are linking an article from 2011 and season 2 was starting around that time. If you check those comments, they talk about Luna being evil in the episode that was going to air at that time: Luna Eclipsed. Those were really different days and speculations were off the rails at that time, I wasn´t even there at that time but seeing those comments in hindsight put me a smile on my face about their reactions towards the reveal of Luna.
Tons of twists have happened since then, even the opinion towards her has changed abruptly despite being an all time fan favorite.
