People who obsess over people they hate via Facebook
I have a friend who likes to see what her "friends" are up to, only they're not her friends. They're people she judges, dislikes or ever despises. She is constantly telling me "OMG , did you see those pics from Bob's party! He is sooo gross...." etc.
If it's not judgement, it's envy "I see Jane got a new car. How does she afford that? Must be her new GF... " etc.
Ok...Bob is gross, so hide him. Jane make you feel like shit about your own life, so hide her.
Why are you following people you don't even like?
Why are YOU friends with her?
Imagine what she says about you, behind your back.
You have the answer, OP.
On the contrary OP, if you ignore people who hate you, they will get you. It is a matter of self-preservation to know what they are up to.
Hatred observes with more care than love does.
I use a fake name on my FB. It is killing some people who can't look me up. I do enjoy reading the pages of ex-friends. Satisfaction and I get to tell myself "Ha! I called it!" Love when they prove me right. Sometimes I check their Pinterest accounts and smile ear to ear when they post a 'want' that I've had for years. Living well really is the best revenge.
