Indeed.
As folks talk about their favorite magic bullet to "solve" the problem,
they need to take note of the above point. It exemplifies why the task is
difficult:
* Some spammers are subject to local laws.
Many are not.
* Some spammers are relatively cooperative and
seek to have a reasonable good community
relationship. Many do not.
* Some spammers are straightforward and even
cooperative. Others are highly deceptive.
So as we suggest mechanisms, we need to think hard about how effective they
will be and at what cost.
