What should ISPs ASPs MSPs xSPs do?

[sean at donelan.com (Sean Donelan)]

Other than the usual damned if they do, damned if they don't; is there any 
rough consensus about some practical things ISPs, ASPs, MSPs, xSPs 
(and customers/users) should do or should not do?

Or is it just rough consensus what other people should do, but you'll get 
upset if that rough consensus stopped you from doing something?  Stop 
stuff you don't like immediately, anytime of the day or night; but 
give you years to fix your stuff even if it is hurting other people's 
stuff.
