Sarahah

While posts need to be shared on social media to get responses, users can do less on this messaging-based website than you may think -- but the interactions you get in return may be extremely iffy. There aren't any instructions on how to best use Sarahah, and the FAQ is only five questions long. But Sarahah's confusing functionality is just one of its problems. The site leaves much of the work involved in connecting users to posts and each other to Twitter, Facebook, and WhatsApp. That seems like a thinly veiled way of passing any possible issues off to other sites while attempting to maintain independence from content.

Users can post a topic on Sarahah's site, but random users won't see it, so they can't respond. Instead, users need to share the URL on an external outlet, seemingly to encourage only people they know to weigh in. You can't friend other site users and get anonymous responses from them, or post a question to large groups of Sarahah users. This limitation doesn't necessarily make it a safer experience, though. Since the responses users get when they share items on social media are anonymous, people have carte blanche to say whatever they want -- and reportedly do. Although its creators say the app and website were designed to help people receive private, constructive, and honest feedback, some parents have voiced concern about the app being used to bully kids. With seemingly little to no moderation, clear rules, or other restrictions, it's not hard to imagine how that could happen -- or why Sarahah may not be the best outlet for kids to communicate with.
