Pre database
Public database that logs when, by whom and under what name a warez release was "pre'd".
In the warez scene, "pre" is the moment a release is made available on the topsites. A pre database (predb) indexes these events publicly: release name, group, timestamp and whether the release was "nuked" — rejected for being broken or duplicated. That makes it the scene's timeline seen from the outside, often hours before the files reach ordinary networks.
Sites like predb.org and srrdb are used to settle who was first, spot dupes and prove the age of a release. Above them sits the closed topsite hierarchy; the predb is the window the public gets to look through.
