A wildly popular anonymous messaging app has been removed from the Apple and Google stores after accusations that it has been facilitating bullying. But the company's chief executive denies the claims and says the app isn't meant to be used by younger teens.
Katrina Collins was appalled by the anonymous messages her 13-year-old daughter was receiving. One person said she hoped her daughter would kill herself. Others used extremely foul and offensive language.
The messages appeared on the Sarahah app, which was designed to allow people to leave "honest feedback" about colleagues and friends. Although Collins' daughter wasn't actually using the app, she saw the messages after a friend downloaded it and showed them to her.
Collins, who lives in Australia, put up a post on online petition site Change.org. She called for the app to be removed from two of the biggest mobile storefronts - Apple's App store and Google's Play store. The petition accused Sarahah of facilitating "bullying" and "self harm", and quickly gained nearly 470,000 supporters.
The app was then taken down from both the Apple and Google stores. It appears the companies took action in response to the petition, although a Google spokesperson said "we don't comment on specific apps" and Apple did not respond to requests for comment.
Zain-Alabdin Tawfiq, the CEO of Sarahah, has disputed Collins' allegations. He says the decision by Apple and Google to remove the app was "unfortunate", but is "very optimistic about reaching a favourable understanding with them soon."
Anonymous messages
The app has had an up-and-down ride since it was launched a year ago. It became an instant success - worldwide, more than 300 million users have created accounts. Sarahah, which was developed in Saudi Arabia, topped Apple's App Store in more than 30 countries in July.
Sarahah, which is named after the Arabic word for "honesty", aims to allow users to receive anonymous constructive feedback. But Katrina Collins, the woman behind the petition, says it also "facilitates cyberbullying".
"If it's happening to my daughter," she told BBC Trending, "it's happening to a hell of a lot of other kids out there as well."
A 14-year old from Grimsby in the UK recently spoke out about the "disgusting" messages she received on the app.
Tawfiq says the offensive word highlighted in Collins' petition "would be picked up by our filtering mechanism and prevented from reaching its destination". He says "as soon as we received this petition, we tried to run [the message] through Sarahah, and it didn't go through."
But Collins says the messages about her daughter "definitely sent", and sent screenshots of the offensive messages to prove her point. She said: "There were no filters at all that picked [them] up. They were all sent".
Since the petition launched, Tawfiq says his company has upgraded its filtering system to use "artificial intelligence and machine learning."
"So basically if someone says kill yourself, then 'kill' is a keyword. But if someone says 'jump off a cliff', then now these robots will be able to detect that and block it as well." He also pointed out that the app is meant for people aged 17 and older.
BBC Trending set up an account and sent the phrases used in the messages to that account. None of the offensive language got through, although this may be because of the recent algorithm change.
