Not that I'd ever get involved in something so stupid as Facebook Revenge, but I wonder what you think doing all that will even prove to her other than it will cement in her mind that she's more than glad you're no longer part of her male harem.
First i think you should calm down and begin the process of reflecting on the relationship and pin pointing when there were red flags from her behaviour that you ignored. You do that so that you don't ignore such things in the future in hopes that it's nothing and you discuss negative hints that your gut is screaming at you to get to the bottom of.
Then, you need to stop looking for revenge because looking for anything that has her as the subject is only keeping you mired in your pain and hatred and it will take you longer to get to the stage of indifference to her.
Then keep yourself busy with family and friends and doing the things you've always wanted to do but didn't get to because you were too busy being in a couple dynamic. Get re-aquainted with your hobbies or start one if you don't have one so that you keep your mind off the skank that is her.
The best revenge is living a good and happy life without the likes of her in it. Trust that karma will take care of her and that revenge and inflicting pain on her is not your job.
Be thankful you're away from her and stop doing things that will keep her forefront in your thoughts.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
