posting to usenet . . . not the same as reading

e.g. "newsgrouper", and now "csiph", provides a convenient means for   
posting to usenet newsgroups via any device with internet access and
a web browser . . . but posting to usenet is not the same as reading      
from usenet, which sans the universal "ignore" filter is impractical      
in moderately active newsgroups, to nearly impossible in more active
newsgroups . . . thus is why client-side filtering using a dedicated            
newsreader is essential for no. 1) filtering out usenet's equivalent            
to junk mail, ditto rogue phone calls/distractions/uninvited company, 
by using one single asterisk "*" for any overview header text string 
to set the ignore flag on all articles, in any newsgroup section [*],   
not already whitelisted or blacklisted, all at the user's discretion      
   
probably all newsreader clients allow "ignore" or "watch" filters in    
their "add filter" menu . . . e.g. forte agent (which i still use to    
post, but use 40tude for reading), set filter expression "author: *",
kill action "ignore thread", scope "global", priority "100" or lower, 
this way only preapproved articles (contributors/topics/servers/etc.)       
bypass the global ignore flag, and blacklisted/killfiled "troll farm         
regulars" (some of their myriads of known aliases date back pre-1994)    
are automatically deleted/moved to the junk folder, purged, purified   
                     
usenet is not for everyone . . . it's very old-fashioned, and yet it       
remains popular, especially for those who can use usenet newsreaders, 
meaning those inclined to avoid mainstream media in any form, social       
media, television, radio, psyops, all of which they say, steer clear
