Mona was the "A" torturing the Liars from Season 1-2, with the exception of "The First Secret." Mona was the original "A" who tortured the Liars and founded the "A"-Team, but she wasn't the "A" that tortured Alison. The "A" that tortured Alison was Big-"A"/Red Coat. It's possible that Mona became "A," after finding out Ali was being hounded by an "A" figure via her secret diaries, post-disappearance.
