About This Breach
The 511,290 figure is the public event scope, not the size of LeakData’s local email index.
The MySQL dump in LeakData’s sealed complete source archive has 31 source-authored columns in the users table. The email-only import selects only the explicit address field users.fmail; usernames, passwords, IP addresses and all other profile fields are excluded. Two independent passes over 3,144,942 rows found 509,486 valid email occurrences; 2,361,997 NULL values, 273,443 blank values and 16 invalid values were not accepted. Removing 107 duplicate occurrences produced an exact local index of 509,379 unique canonical emails. No fitting to the public count was performed.
A positive result on this record means that the queried email address exists in the local 509,379-address set; it does not prove that the account is compromised today or that every a public breach source-reported field occurs with every match. If a DragonNest password was reused elsewhere, replace it with unique passwords, enable two-step verification on the email account, and review old sessions and recovery options.
