   Wrong, and not any more dangerous than any other tosser that has Rescan.   
      
   A tosser has an area called ABC. There are three downlinks. 229/100, 229/200    
   and 229/300. A new system, 229/400 joins and Areafixes ABC with a rescan. They   
   get all the messages but 100, 200 and 300 do not because they exist in the    
   Seen-by's in all the messages that exist already, and thus 229/400 is added    
   into the Seen-by's/Path going forward.   
      
   The method used is no different than Gecho, TBBS/Flame and a lot of tossers    
   out there... pretty sure even Fastecho does it this way but perhaps adds some    
   extra kludging to indicate that the message was in fact, rescanned.   
      
   You know very well that there is no fool-proof way for a tosser to offer a   
   Rescan feature, because some Sysop, somewhere, somehow, will find a way to   
   break it or configure things in a way not intended, and we get "dupe-dumps".
