that teens between 13 and 18 should have a parent's permission to use Kik, but there is no technical way to enforce the requirement or to guarantee that a minor will not enter a false birthdate. Kik Interactive has said that it uses "typical" industry standards for age verification, that "perfect age verification" is "not plausible", and that the company deletes accounts of users under 13 when it finds them, or when a parent requests the deletion. Open-source module name In March 2016, Kik Interactive was involved in a high-profile dispute over use of the name "kik" with independent code developer Azer Koçulu, the author of numerous open-source software modules published on npm, a package manager widely used by JavaScript projects to install dependencies. Koçulu had published an extension to Node.js on npm under the name "kik". Kik Interactive contacted him objecting to his use of the name, for which the company claimed intellectual property rights, and asked him to change the name. When Koçulu refused, Kik Interactive contacted npm management, who agreed to transfer ownership of the module to Kik without Koçulu's consent. Koçulu then unpublished all of his modules from npm, including a popular eleven-line code module called "left-pad" upon which many JavaScript projects depended. Although Koçulu subsequently published left-pad on GitHub, its sudden removal from npm caused many projects (including Kik itself) to stop working, due to their dependency on the Node and Babel packages. In view of widespread software disruption, npm restored Koçulu's left-pad and made Cameron Westland of Autodesk its maintainer. The incident sparked controversies over the assertion of intellectual property rights and the use of dependencies in software development. Cryptocurrency Kin is an ERC-20 cryptocurrency token issued on the public Ethereum blockchain. Kin was first announced in early 2017 which marked a pivot in Kik's strategy, a response to difficulties faced from competing with larger social networks such as Facebook. Kin was launched in September 2017 with an initial coin offering (ICO) raising $98 million from 10,000 participants. The purpose of the token is to facilitate value transfers in digital services such as gaming applications and social media, and was initially launched on Kik Messenger to leverage the application's 15 million monthly active users. The enforcement division of the U.S. Securities and Exchange Commission considers the cryptocurrency offering to have been an unregulated security issue and is expected to begin legal action against the
