Based on what? My experience, and I have TONS of it, is that it DOES
help, tremendously, to fight usenet spam.
That's your opinion and I find it to be untrue in my experience.
Legally, NO ISP is open to legal action for enforcing their TOS. At
least any ISP that resides in a civilized country.
At this point in fact, the main offender as far as not enforcing their
TOS is Google.
My experience is based on years of reporting each and every incidence
of both usenet and email unwanted messages. About one in ten was
answered by the abuse people but usually an auto response. I never saw
any reduction in the spam I was reporting. I gave up worrying or
reporting email spam about five years ago when I found a simple
solution. As for usenet spam I don't follow many groups that suffer
too much spam. I also use Agent so spam threads are a single key
ignore.
As for legal action, it's not TOS related. I am currently involved
trying to stop a marketer using virus techniques. His ISP refuses to
do anything about him because they have a legal contract with him. The
ISP is in the USA. Is that a civilised country?
