You're lucky. I deactivated back in January and I think I did a "log in with facebook" button once and now facebook seems to have re-activated my account implicitly.
Also they send me click-baity emails like "John Doe has posted a status update!"
Heck, they've even started TEXTING me to lure me back.
I'm dreading having to log back in to try to figure out how to get them to stop trying to contact me.
