Following a spate of high profile bullying cases and suicides that were linked by pundits to the service, Ask.fm has been taken over by Ask.com and social dating app Tinder.
IAC, which arranged the deal, said it plans on spending millions on improving the safety of the site, while Ask.fm's founders are due to leave. It will "revamp" its safety policies and procedures, according to an official safety agreement between the new owners and New York state attorney general Eric Schneiderman.
Ask.fm, the BBC reports, started in 2010 and has a hefty userbase of 180 million per month - but complaints surfaced after it was linked to the deaths of teenagers and online abuse. But IAC said it will focus on child safety, including by employing more moderators.
