YouTube initially responded last week by removing tens of millions of comments. along with more than 400 channels, on videos involving minors. The revelations also triggered a sharp backlash among major brands that advertise on YouTube, including Nestle and Disney, which suspended their ad spending on the site.
The revelations also led to local backlash, with Spark pulling its marketing activity from YouTube.
Adding further controversy to YouTube's local presence is the effect that the so-called Momo Suicide games are having on children.
The "Momo" character - a scary doll's face holding a knife - interrupts shows and threatens viewers. It has appeared on Fortnite, Peppa Pig and other popular YouTube videos and warns children if they tell their parents then their family will die.
Earlier this week, an Auckland mother has posted heartbreaking footage of the emotional toll that watching the "Momo" suicide game has had on her children.
On Thursday, YouTube said it had accelerated its work on new software that could spot and remove predatory comments more effectively, adding it had terminated additional channels that put children at risk. The company said it would grant an exception to its new comment ban for a "small number of channels that actively moderate their comments and take additional steps to protect children."
YouTube has long struggled to monitor and remove problematic content from its massive platform, where users upload 400 hours of content every minute. In recent years, it has faced controversies over militant extremist content, hateful conspiratorial videos and violent, sexually suggestive clips that were reaching children. A coalition of consumer and privacy groups filed a complaint last year with the Federal Trade Commission alleging that YouTube also is violating the nation's child privacy law by collecting data on kids under the age of 13.
Since the video blogger documented how paedophiles shared time stamps of sexually suggestive moments, a parent in Florida found that a clip explaining how to commit suicide had been spliced into children's videos on YouTube and You Tube Kids, an app specifically designed for children.
