!x! was implemented as a shorthand for the internet standard

x-no-archive

which is an optional tag which is supposed to prevent long term  
storage of an email (often ignored). I implemented it in findU many  
years ago as a way to allow hams to opt out of having their positions  
stored on findU, while allowing full use of APRS and the APRS Internet  
System. I added !x! in order to allow mic-e users to add it to their  
comment text and still leave room for other text. I do not know if  
other internet databases like aprs.fi, and openaprs implement it.

I strongly object to using this same feature to prevent a packet from  
appearing on the APRS Internet System. No IGate software should be  
filtering on this. Years ago we settled on NOGATE and RFONLY as the  
ways to prevent packets from appearing on the APRS IS.
