a Facebook user who keeps turning their profile on and off like a light switch and blocks and unblocks people just to snoop around in someone else's life and keep others from finding out where they've been sneaking.

He blocked me so I wouldn’t know he was chatting with his ex.
I unblocked my mom just so she wouldn’t realize I’d been talking to my crush.
