Hi,

everybody should be able to post wathever stupid
messages they want.  Who is going to decide what
is stupid and what is interesting?  You?
As long as it is related to Ruby (not spam) everybody
should have the right to post.
If you think somebody doesn't behave according to groupiquette,
you could send him a friendly post, explaining clearly why
you think some posts may not be appropriate (not anonymously).

If you like personal wars, have a look at comp.lang.asm,
which makes for interesting reading.
