Soo why the fuck am I receiving notifications about someone from my contacts is available on messenger, when you don't fucking have the permissions to read my contacts? I'm looking at you Facebook Messenger.

That's some new level of ignorance. "Oh I see you didn't gave me the permissions to read your contacts. Worry not my friend just let me take a secret peek of it. I will be discreet, I promise!"... Well FUCK YOU!

P.S.: I only use that piece of garbage because unfortunately some of my friends are only available there... Time to convince them to switch.
