RE: Kik : The messenger app launches Kin an Ethereum based Token

Thank you. I know there was a controversy in 2014.

This is from Wikipedia about the app:

Child exploitation[edit]
Child exploitation is prominent on Kik Messenger, causing law enforcement and the media to frequently express concerns about the app.[42][43][44][45][46] Automated spam bots have also been used to distribute explicit images and text over Kik Messenger.[47][48] A state law enforcement official interviewed by The New York Times in February 2016 identified Kik as "the problem app of the moment".[8]
Prior to 2015, Kik Interactive addressed this issue by informing parents and police about their options to combat child exploitation. In March 2015, the company adopted a more aggressive strategy by utilizing Microsoft's PhotoDNA cloud service to automatically detect, delete, and report the distribution of child exploitation images on its app.[49] (Some experts have noted that because PhotoDNA operates by comparing images against an existing database of exploitative images, it does not effectively prevent "realtime" online child abuse and may not detect material not yet added to its comparison database.[50]) Kik Interactive also began collaborating internationally with law enforcement by joining the Virtual Global Taskforce, a partnership between businesses, child protection agencies, and international police services that combats online child exploitation and abuse.[3][49] The company also sponsors an annual conference on crimes against children.[8]
