Video-conferencing platform Zoom has joined a counterterrorism organization formed by major U.S. tech companies including Meta Platforms Inc (FB.O), formerly known as Facebook, and Microsoft Corp (MSFT.O), the group said on Wednesday.
The Global Internet Forum to Counter Terrorism (GIFCT) is an independent group through which member companies share information to combat terrorism and violent extremism on their sites.
GIFCT’s founding members were Facebook, Microsoft, Twitter (TWTR.N) and Alphabet’s (GOOGL.O) YouTube.
Its membership has risen to 18 companies with five new platforms joining this year including home-rental firm Airbnb (ABNB.O), social network Tumblr and online publishing platform WordPress. It said it plans for more in 2022.
Tech companies have long been criticized for failing to curb violent extremist activity on their platforms, though they also face concerns over free expression.
GIFCT was created in 2017 under pressure from U.S. and European governments after a series of deadly attacks in Paris and Brussels.
It manages a hash-sharing database, where member companies can share “hashes”, unique numerical representations of original pieces of content that have been removed from their services. Other companies can use these hashes to identify the same content on their sites and review or remove the material.
“It is our responsibility to support our users and protect them against online threats,” Josh Parecki, Zoom’s associate general counsel for trust and safety, said in a statement.
“By collaborating with other leaders across the industry, sharing key learnings and advancing research, we aspire to make the digital world a safer place for all.”
These ranged from abuses like “zoombombing”, where uninvited users crashed others’ calls to share hate speech and racist, violent or pornographic content, to decisions like its cancellation of a virtual event featuring Leila Khaled, a member of a Palestinian group on the U.S. State Department’s list of terrorist organizations.
GIFCT Executive Director Nicholas Rasmussen said in a statement it was delighted to add Zoom as its mission “requires we work with a diverse range of companies …to develop cross-platform solutions that render terrorists and violent extremists ineffective across the internet”.
GIFCT has faced criticism from some human and digital rights advocates over centralized or over-broad censorship, and calls for greater transparency.
In July, the organization expanded the scope of its hash-sharing database to include attacker manifestos and other publications and URLs flagged by the United Nations initiative Tech Against Terrorism. It also said it would continue to broaden the database to include hashes of audio files or certain symbols.
GIFCT also said on Wednesday it has designed a new membership structure based on company revenue, with suggested annual contributions ranging from $0 to $1 million. It said membership was not contingent on a company’s revenue.
Other members include Meta’s Instagram and WhatsApp, Pinterest (PINS.N), Amazon.com (AMZN.O), chat platform Discord and file-sharing service Dropbox (DBX.O). Other companies such as Reddit and Snapchat-owner Snap (SNAP.N) can also access the hash-sharing database.
