That is not entirely correct. If you take into other newsgroups other
than the ones you had already mentioned this is nothing, I have seen
ng were there had been over 5,000 posts in a month and 80% of it is spam,
the "women in bio" ng is one of the smaller ng around so any amount of
spam that get sent here would obviosely boost the percentage level over
other bigger ng. A very simple mathematical logic....:)
