I hate social media: Clemence Poesy

"Harry Potter" actress Clemence Poesy has revealed she hates social media.

The 33-year-old actress thinks sites such as Instagram and Twitter are incredibly "self-centred" and are having a negative impact on society, reported Female First.

"Selfies will kill us. I really didn't want to join but there was a fake account that people started believing was mine.

"I only post covers of books, posters for films and sometimes music. I try not to use it as a tool for endless self-promotion. I think it's going to change our brains, but not for the better.
