Well, from my relatively limited experience in this
from when I ran an ISP and had half a dozen customers
who asked for it (as was their right by Texas law),
I can say for sure that manually maintaining a block
list is a losing proposition.  You need to subscribe
to some sort of service that keeps these things up
to date.  They will block relay sites as well as
end-user sites.

You know all the usual suspects - cybersitter,
cyber patrol, surfwatch, netnanny etc...
