Since the WinLink objects all use the ARRL symbol with W overlay it should be
possible to filter them out with the "-s//a/W" filter string ("do not pass 
posits from stations with the a symbol from the alt table with W overlay").  
See http://www.aprs-is.net/javAPRSSrvr/javaprsfilter.htm for details.

Since these objects will only come in over a server port, that seems the 
right approach -- just tell the server to not even send them to you.
