Business" on Fast Companys 2017 list. Controversies Use by minors with explicit content Like many other social media services Kik has garnered negative attention due to instances of minors exchanging explicit messages and photos with adults causing law enforcement and the media to frequently express concerns about the app. Automated spam bots have also been used to distribute explicit images and text over Kik Messenger. A state law enforcement official interviewed by The New York Times in February 2016 identified Kik as "the problem app of the moment". Police said they found Kik's response frustrating and one detective said obtaining information from Kik was a "bureaucratic nightmare".

Kik has been criticized for providing inadequate parental control over minors' use of the app. The ability to share messages without alerting parents has been noted as "one of the reasons why teens like Kik". Parents cannot automatically view their child's Kik communications remotely from another device, but instead must have the password to their child's user account and view the communications on the same device used by their child. As of February 2016, Kik's parents' guide stresses
