Unreliable website 8Shit posted an article titled "On August 1, Sarahah Will Reveal The Names Of The People Who Sent Messages" which opened:
The app turned out to be a social experiment by the CIA.
Palo Alto, CA.- There's a new app ruling all app stores: Sarahah. This application allows you to anonymously send messages to anyone registered, without them "knowing" that it was you. Unlike ask.fm, there's no way to let them know that it was you who sent the message, and there's no way to reply messages.
....
But this is all a social experiment made by the CIA. And they're planning to release all the names of the people who sent messages:
This was followed by a screenshot of a (fake) tweet:
The fake tweet was probably created using this website where anyone can create fake tweets seemingly coming from the @SarahahAPP account. Note that there currently is no such account on Twitter, apparently it has been suspended and it probably never was an official account for the app anyway.
The actual website for the Sarahah app does not list a Twitter account, just a Facebook page. And literally the first message there is a link post pointing to an article on the Sarahah website titled "In Sarahah Revealing Names ?". Relevant quote from that article:
Many User Are Saying that Sarahah App is Revealing the Names of the User Who Sent a feedback Messages to Anyone. Many of You are Also send a Messages Which are not Good. So Don't Worry Sarahah is not Going to Revealing the Names. Someone Reveal the Fake News that Sarahah is Revealing the Name of the Person Who send a Messages to Anyone. So Truth is that Sarahah is Not Revealing the Names.
Despite the broken English the message seems pretty clear: Sarahah will not reveal the names of the people who sent messages with it.
But the fake story seems to have caused quite some panic as the Trendolizer graph at the end of this article shows, with hundreds of people sharing the hoax. If you notice anyone spreading the rumor around you can help by pointing them to this article here because nobody likes being fooled into deleting an app because of fake news.
