I just popped into a science based newsgroup that I read occasionally, and I
was appalled to see that you can hardly find the legitimate posts anymore
because it is so over-run with spam and unrelated garbage. We get people
now and then who drop spam in here or multi-posted totally off-topic stuff,
but after seeing that, I think we're pretty lucky that 95% of our posts here
are still related to GH or spin-offs from legitimate posts.
