   After migrating from Avon (Paul's) Usenet service which was announced to be   
   sunset, when using real usenet provider I learned folks abuse non binary   
   groups to send binaries.   
      
   I blew through a 25GB quota in less than 30 days, due to approx 400 messages   
   posted in comp.lang.c++ was actually a multi-part yEnc encoded binary posted   
   to multiple usenet newsgroups including comp.lang.c++   
      
   Sample text from such messages   
      
   =ybegin part=270 line=128 size=104857600 name=Supermarket Simulator   
   1-0-1.part01.ra   
                                                                              ▒   
   =ypart begin=103296001 end=103680000   
      
   Although the message size seem to vary, some were large 400,000 Bytes and   
   larger; so having a size limit may also be a way to fight this abuse.   
   Although, some of the messages seem normal size 26667 bytes which leads me to   
   believe newslink isn't capturing all the data in the message base (which is   
   good); but I'm sure it is pulling (requesting) it from the USENET provider   
   hence me blowing through my quota.
