There was a photo on my news feed of a girl I'm friends with on there. The photo was within an album of her friends. She and her friend had commented three times on it 'I look like my mum' etc.
When I clicked on it though it was part of some radio stations public photo album and there was about 40 comments below it from strangers suggesting that it was Christina Aguilera and stuff like 'she got fat' and 'no way is that her'. The girl in question wasn't tagged in it nor was there any single reference to her mate either.
I clicked back onto my news feed then clicked the photo again, and it was as it should be, a photo within her mate's album and the three original comments I mentioned before WTF just happened. It was creepy.
