SYDNEY, Aug 6 (Reuters) - Australia's internet watchdog

has said the world's biggest social media firms are still

"turning a blind eye" to online child sex abuse material on

their platforms, and said YouTube in particular had been

unresponsive to its enquiries.

In a report released on Wednesday, the eSafety Commissioner

said YouTube, along with Apple, failed to track the number of

user reports it received of child sex abuse appearing on their

platforms and also could not say how long it took them to

respond to such reports.

The Australian government decided last week to include YouTube

in its world-first social media ban for teenagers, following

eSafety's advice to overturn its planned exemption for the

Alphabet-owned Google's video-sharing site.

"When left to their own devices, these companies aren't

prioritising the protection of children and are seemingly

turning a blind eye to crimes occurring on their services,"

eSafety Commissioner Julie Inman Grant said in a statement.

"No other consumer-facing industry would be given the

licence to operate by enabling such heinous crimes against

children on their premises, or services."

Google has said previously that abuse material has no place

on its platforms and that it uses a range of industry-standard

techniques to identify and remove such material. Meta - owner of

Facebook, Instagram and Threads, three of the biggest platforms

with more than 3 billion users worldwide - says it prohibits

graphic videos.

The eSafety Commissioner, an office set up to protect internet

users, has mandated Apple, Discord, Google, Meta, Microsoft,

Skype, Snap and WhatsApp to report on the measures they take to

address child exploitation and abuse material in Australia.

The report on their responses so far found a "range of

safety deficiencies on their services which increases the risk

that child sexual exploitation and abuse material and activity

appear on the services".

Safety gaps included failures to detect and prevent

livestreaming of the material or block links to known child

abuse material, as well as inadequate reporting mechanisms.

It said platforms were also not using "hash-matching"

technology on all parts of their services to identify images of

child sexual abuse by checking them against a database. Google

has said before that its anti-abuse measures include

hash-matching technology and artificial intelligence.

The Australian regulator said some providers had not made

improvements to address these safety gaps on their services

despite it putting them on notice in previous years.

"In the case of Apple services and Google's YouTube, they

didn't even answer our questions about how many user reports

they received about child sexual abuse on their services or

details of how many trust and safety personnel Apple and Google

have on-staff," Inman Grant said.
