Is it wrong to log into an Ex's facebook account?

[Sarah]

My friend has herself convinced that it is okay to log into her old boyfriends facebook account. He has changed his password, but she figured it out. She goes through his messages and pictures. She doesnt post anything but i still feel that as a friend i should help her realize that it is wrong. I thought maybe another opinion would help. Also, should i shut up about it, and let her continue, or should i tell her my views on what she is doing?

Yes, it is very wrong. She could even face criminal charges because of it, and spend time in jail. You should tell her.
