YouTube, one the UK's
top social media sites, has been hit by thousands of
pornographic videos in what is believed to have been a co-ordinated
attack by a satirical online group called 4chan.
4Chan is an organised group that has been described on online
message boards as "sick" and "horrifying stuff", according to the
BBC.
Google, YouTube's owner, said most of the videos have been
removed, but some could remain accessible for days as it sifts
through the system to clean it up.
The attackers used popular celebrities such as Hannah Montana to
lure YouTube users to the videos, but innocent footage soon turned
into something much steamier.
Google said any account set up to attack YouTube in this way
will be disabled, but it may take some time for video search
results and thumbnail images to disappear from the site.
