All the newgroups listed are engaged in openly trading ILLEGAL child pornograpy.
Those are very good questions.
I cannot render the definitive answer, but I have always felt that MONEY and FEAR both play a large role in why these illegal newsgroups exist and thrive. The FEAR of losing users who access these illegal groups and the loss of the MONEY that these same users pay. In effect, children are being exploited on the internet for profit. That is, of course, merely my opinion.
For a definitive answer I strongly urge you to write to your Internet Service Provider (ISP) and inquire why they tolerate and facillitate illegal child pornography on their networks and systems.
