RE: FBI tells the public to call their ISP for help

In the 2+ years I have been working for an ISP I'm not aware of one customer
that has gone over to one of our competitors because we identified and cut
them off for an abuse issue.  Most of them have been very grateful that we
identified a problem and are earnest in resolving it.

And for those who don't care?  In a slight variation on an oft-quoted
statement in this listserv, "I want my competitors to have them."

There's a major problem with this - End-users won't take nicely to being
restricted from going to specific websites, and will more than likely go to
another ISP rather than to patch their computer as they see no benefit of
patching themselves. We see the benefit of the patches, they don't

Not to single anyone out but there will more than likely always be a
(and/or clueless) ISP who doesn't care if over half their network is wormed,
the customers from the ISPs who are cracking down on infected machines will
simply go over to the ISP who doesn't care as there would be "less hassle".
What needs to be done is ALL ISPs accross the board need to clean up their
networks, thus cornering the lazy end-users into cleaning up their machines.

To be honest: There's too few ISPs that would want to take up the
responsibility of filtering worm'd customers, and as well, the instant an
starts filtering, they may even set themselves up for a lawsuit of the
customer saying "I paid for the service, why aren't I getting it?!"

And reguarding Microsoft and their patching licences:
Those patches may be their precious "legal property" but it's their hording
legal rights that's damaging hundreds of thousands of computers. Microsoft
currently abusing their market share standings and giving insufficient patch
distribution, (i.e. offline distibution) Therefore Microsoft should be held
accountable for every computer that becomes infected with worms due to
insufficient patching. To me, it sounds like Microsoft wants the power, but
doesn't want the responsibility that comes with the power of great market
share. It is time Microsoft be forced to take that responsibility.
