Internet Against extremist videos

Some of the Tech Giant like Facebook,YouTube and Google are taking steps to remove/block videos containing extremist content 

For those who don't know what extremist means it means belief in and support for ideas that are very far from what most people consider correct or reasonable

The moves is taken because of the pressure from governments around the world over big websites.

Facebook and YouTube are among the sites which already started creating scripts and programs to takedown videos from Islamic state and other extremist propaganda videos.

President Barack Obama asked the internet's social-media giants to help preventing terrorist attacks by monitoring and examining hateful content and removing speech as well as terrorist activity that appears on their networks.

Question stands how they will do it?

Originally they are using a software which was created to identify and remove copyright content over Facebook,YouTube or any other site. The software looks for "hashes," a type of unique digital fingerprint that companies automatically assign to specific videos, allowing all content with matching fingerprints to be removed rapidly.Two sources familiar with the process told the news agency. Such technology could be used to prevent reposts of content already deemed unacceptable but not identify new extremist content.

EFFORTS:

Facebook has assembled a team focused on policing terrorist material and has promoted counter-speech

Twitter has suspended more than 125,000 accounts associated with terrorism

Google has said it will display counter-terrorism adverts against searches for extremist material

Telegram, an encrypted messaging app, says it has shut down Islamic State propaganda channels

Anonymous, the hacker organisation, has declared "war" on the Islamic State and claims to have helped prevent attacks

Latest update:

Facebook, Twitter, Microsoft and YouTube in May agreed to a new European Union code of conduct that takes aim at illegal hate speech and terrorist propaganda posted online. Under the new rules, they have committed to reviewing within 24 hours of receipt the majority of notifications about a social media post that may contain hate speech. They've also agreed to remove the post if necessary.
