There are some real morons on Usenet. Most newsreaders have a Block Sender option so you don’t have to look at their stupid posts, but the worst ones (hello Matthew Goodyear) change their (alleged) email addresses regularly. And some poor fools keep responding to these trolls, so you still end up seeing a lot of garbage posts.

What newsreaders need is

• An option to hide messages written by a particular person, and any responses to those messages
• An option to hide messages written by a particular person, nominated by their alias (name), including wildcards, and not their email address

I wonder if any Windows newsreaders do this already?
