Ingenious plan, will she suspect me?

My girlfriend wronged me really really bad. She cheated on me and left me for the new guy. And then she blamed all of it on me. I was nothing but sweet to her. But two can play at this game. I'm good with computers. I hacked into her Facebook account (Facebook programmers are pathetic) and recovered her password. With that password I was fortunate enough that it matched her Apple ID password. I hacked into her Iphone and can send messages from her phone remotely to other people. I could text her boyfriend from her phone, or whoever, and people will think its her. I would do this from a public computer with no security cameras to be untraceable. Kinda like I'm now. She has two ex-boyfriends and maybe other people who don't like her. She never knew I was good with computers. But it will probably be kinda obvious its me. But at the same time my plan is so ingenious and she can't prove anything so I should not care. Plus I'm not going to be evil, just send a few funny things to people to put her in awkward situations. Should I do it?

Added (1). And please don't tell me revenge is not the answer, i know its not. I just want to know if it is too blatantly obvious to do it?

No. You really shouldn't do it… I'm sorry but that just sounds too obvious. I guess if you really really feel like you need to do anything, just talk to her and just confront her about how she blamed you for everything. Cuz honestly, you might ruin this girl's life if you decide to send anything too harsh. I know it's not what you want to hear but it's what you should hear.

It would not be blatantly obvious but I don't think you should do because its not fair on her, revenge/ anger isn't the answer it just eats you up in side and makes you feel depressed and evil, it sucks your life away.
Think about if it was you in her shoes, how would she feel if she knew that someone she trusted was doing that her?
I don't think you should do it at all
