NJZ has taken a strong stance against harmful online activities directed towards its members. The group's legal representative, Shin & Kim LLC, released a statement on March 24th KST, expressing concern over the proliferation of false information and defamatory posts, especially targeting minors associated with the group. The firm mentioned that they are closely monitoring various online platforms to track down anonymous perpetrators and are cooperating with authorities to hold them accountable. They have also vowed to take legal action, both civil and criminal, against those responsible for spreading false information, defamation, and insults.

The legal representation covers Minji, Hanni, Danielle, Haerin, and Hyein, and stressed that any detrimental actions against the group will face severe legal consequences. Fans and well-wishers are urged to report any malicious content by providing URLs and PDF files of the objectionable posts to the law firm's designated email address.
