Is that true? Synchronet/SBBSecho uses 2 methods of dupe messge detection:
1. Message-ID (in the case of FTN, that's everything between "\1MSGID: " and
the CR) - the Message-ID doesn't change when messages a re-scanned
2. Message body text (not including kludge/control lines, paths/seen-bys,
and tear/tag/origin lines)
Rescanned messages would (should) be caught as dupes just fine.
