About This Breach

Its ten reported classes are birth dates, emails, gender, geographic locations, IPs, races, relationship statuses, sexual orientations, spoken languages, and usernames. Password and payment data are not classes in this record.

The local import measure is 2,464,236, a difference of 1,403,761 below the external measure. Neither figure means unique people, active members, profiles, subscriptions, or rows containing every field together. Presence of one field does not establish that other demographic or intimate fields occur for the same person.

A row establishes only actual fields in the 2015 dataset. It does not establish identity, an Adult FriendFinder account or membership, sexual orientation or conduct or relationship status, race, gender, or language, location, IP, or username ownership, field co-occurrence, password or payment data, harassment, extortion, or misuse.

Adult-service, sexual-orientation, relationship, race, gender, location, and identity links require the strictest private handling. Correct profile details do not authenticate a sender. If actual harassment, threats, or extortion occur, evidence should be preserved and trusted platform, legal, specialist, or emergency support appropriate to the circumstances should be used.

Verification and editorial method

LeakData compares the incident name, date, affected-record count, and exposed data types with accessible sources. Unverified fields are not presented as facts, and records are updated when new evidence becomes available.
