I don't get it. What is the motivation to causing the newsgroups to
be flooded with these nonsense messages? Is this one of those things
where people do it because they can?

This periodic flood is making this group nearly worthless to me. It
is hard to find the threads in the midst of the debris and it can be
even harder to find valid messages withing a thread.

I assume there are no solutions to this, right? Or is there a way to
filter out the nonsense?
