Right. Having some data leaked isn't really a boolean, leaked/unleaked. It's a list of leaks, and the implicit map betweenyl your datapoints, whether by intra or interprovider mapping

For example a forum might leak a map between your mail and a password; Implicitly your affinity for that forum's topic is also now on the public record, additionally if your posts were public but under a pseudonym, that might be now known by a sufficiently motivated attacker.

Finally this may be linked with other public datasources like your public tweets or public state records, or even other leaks.

This is why the meme about all ssn's being leaked or about a list of all valid phone numbers is so asinine.
