Have you "quit" Facebook? When and Why?

Meaning, have you deleted your account? I did, and for a couple of reasons:
Pragmatically, for job-related background checks, and once because a new-beau said he “Facebook-stalked” me, his words, and the only dirt he brought up was “You were such a hippie!” Still, kind of rude. I also deleted my Twitter account and Google+ due to the job stuff.
More personally, because in the last couple of weeks, I had former childhood friends who “added” me (or attempted to) who I really thought had written me off. Maybe I’m too sensitive, but where my head is at that if they wanted to re-connect, they could have called… I’ve had the same phone number for many years, live at the same address and I have both a personal website, email and friends-of-friends who they could’ve hit up to get in touch with me. Honestly, I just found it offensive.
So, have you ever deleted your social media presence? If so, why? Do you regret it? Do you feel liberated?
I do have one slight misgiving, and it’s that I put up a page of my design work, but I didn’t really have much on it, never posted any updates, and I don’t think it was garnering an excessive amount of traffic, anyway.
