It would be cool if there was such a feature, which would allow to give a score
to some authors for usenet messages. With that, each author has a registered
"value", and you can show a score for a thread by adding the negatives and
positives scores from each author, avoiding the threads where known trollers
have posted many messages.

Way to implement that:
-on each message, there should be the possibility to right click, and either
"lower the score for this author" or "raise the score for this author".
-each author has a registered score which shows after of before his name, and a
global score for the thread whould be calculated and showed on left side of the
thread.

With that you can also create filters to hide posts from authors with a bad
score, to emphasize authors with a good score, and the same for the threads.

KNode has this feature, and i find it pretty cool (but i don't like the way it's
implemented in it).
