Depends on the relative costs. See below.

That depends - how long will you bet able to get an upstream which doesn't
cancel your service for failure to deal with the problem? That, more than
anything, is the opposite pressure cost - if it costs these places less
to allow spam than to prohibit it, because nobody whacks them with an AUP
saying "your efforts are insufficient", well, they're a business - they'll
go with what's cheaper.

All the time, around here.

Summary: as with every other natural resource, 'the commons' are now held
under market rule. If it turns a profit to spoil them, it will end up
happening. The question is how to make it more costly to permit spam than
to deny it.

And on that note, it's the same old tune, and is no longer operational.
