Finding a GoDaddy account owner without login or contact details requires a multi-pronged approach. Begin by conducting a WHOIS lookup, even with privacy enabled, to identify any accessible contact details and confirm the domain registrar. Explore GoDaddy's account recovery process and contact their support, providing proof of association and explaining the situation. In parallel, pursue internal investigations, such as examining past records for prior domain managers or exploring relevant LinkedIn profiles. Investigate DNS records, associated websites, and social media handles for potential contact avenues. Emphasize establishing unambiguous legal domain ownership and, where applicable, consider contacting GoDaddy's abuse department with substantiating evidence. If infringement or demonstrable harm exists, legal recourse should be considered. Recognize that outdated registrant data can impede recovery and that legal requests must align with GoDaddy's established prerequisites.
