This division of the curator's index gathers adult introductory and companion-finding services — a category that exists across many directories but is rarely organised with care. Entries span dating platforms, personal-ad publishers, and social-discovery applications. The section is maintained as a factual register of operating sites rather than a recommendation service. Visitors browsing here should apply their own judgement, as the index verifies domain activity but not the character of the services on offer. With 31 entries it is one of the smaller but consistently browsed sections of the Keystone28 catalog.
