I've no idea how that's happened, there's no way someone can unblock themselves once you've blocked them.
Does anyone else have access to your account, do you leave yourself logged into Facebook and leave your phone/laptop unattended ??
Just block them again :)
It's strange Giz. I removed her from my friends list then all of a sudden I was seeing her timeline page, so. I checked my friends list and there she was.
It's def not something that they could have done from their end ... it's either a glitch on Facebook's side, or someone has accessed your account ..... the mind boggles .....
FB is bizarre -I've had people recently 'accept my friend request' when I've never sent them one, OH has had friends appear on his friends list that he has not accepted or even seen friends requests for. Best to just block the person again I think
I'm seriously thinking of closing my FB account as huge issues with privacy, I've deleted all 'friends' I've never met in person after getting vile private messages which I think originated from 'friends of friends' and started after I stupidly posted on AB the name of my Business FB page. It just seems as if however much you tweek your privacy someone or something gets around it.
