But instead you prefer a "lazy" NOC, where you need manual intervention in

No, instead I prefer to do all route filtering on my (cust) side, and have
the ISP do filtering based on AS PATH, be it ^CUST-AS_ or configured off
the RADB......

(Well, if a customer is accidentally leaking a full table then ^CUST-AS_
 will still match everything they send you...)

True, but my point is that if ISP is doing filtering based on ^CUST-AS_
they should be implementing _some_ sort of protection against full table
leaks.
