Nazi-hunting group Simon Wiesenthal Center has appealed to popular social media communities to try harder in combating abuse on the networks.
The group pointed to an amount of 20,000 hashtags and handles present on Twitter during 2013 linked to terrorist and extremist activity.
The rise in social media hate speech has increased with 30 per cent, according to the center.
Abraham Cooper, associate dean at Simon Wiesenthal Center, in California, said: “If we want to make it tougher for the terrorists to recruit, we need (actions by) Facebook, Google, Twitter and YouTube.”
In Cooper’s opinion, Facebook is faring far better in censorship than its fellow networks, but scored an A minus on eliminating digital prejudice.
The group received no response on its pleas from Twitter, which was graded an F.
YouTube was rated slightly better with a C minus because its terrorist tutorial videos keeps it from being considered a safer community.
HumanIPO reported earlier this week how Seun Osewa, founder of Nigerian social network Nairaland said he censored comments which could lead to extreme activity.
He said: “If it is a crime to try to discourage people from posting comments that could lead to lost lives, then we are certainly guilty.”
Osewa related his responsibility of censoring posts with the recent garri activist saga in Nigeria.
“The bad guys know how to use Facebook and Twitter,” Cooper added, relating to the promotion of violence.
Founded in 1977 by Nazi hunter and Holocaust survivor Simon Wiesenthal, the Simon Wiesenthal Center recently published the data in its 15th annual report on digital hate and terrorism.
