<human>: My friend, Jessica, installed Tinder out of boredom and she met a guy there and they're now constantly chatting. She eventually gave her facebook to him and they mostly talk there now instead. Jessica was really gushing about how nice this guy is; told me that he was a hopeless romantic, but been cheated on before by a girl (and what a coincidence, the girl has the same name as me!) so he stayed single ever since. Jessica also told me that this guy fessed up that he was falling for her. I thought "that was quick." They were only talking for like a week! But whatever. I just said that I am happy for her and if I can see how this bloke looked like? She happily showed me his facebook page and I almost fell off from my chair. It was my ex!! He tweaked his name a little bit though. For example, his name was actually Alex Dickhead but the name he gave to my friend was Alexis Dickface. 

I was sooo horrified but I immediately spilled all the details to Jessica (we've only been friends for 2mos so yeah that's why she didn't know) I told him that Alex was my ex bf but that was a long time ago and he got a gf now. Jessica was really pissed because it was clear that Alex was cheating on his gf. I don't know why, and I am not proud of this, but I didn't  stop Jessica (she's really into computer so it was really easy for her to do this) from hacking Alex's (2nd) facebook account. 

Hacking into Alex's account was such a vile experience though. He was sending nasty messages to different girls, begging to have a phone sex conversation with him. 

Jessica wants to screen shot all of those and send it to Alex's gf or just simply give her his email account and password, but I just don't know of we are in the place to do that. Should we though?

Summarize the given text in a few sentences.
