[ppml] Proposal: make Abuse Handle *REQUIRED* for AS Registration
There are definite cases where using AS contact info for directing
abuse/securty issues is NOT appropriate.
Case in point:
These jokers had their own AS # and were probably the biggest source of open
proxy scans for this year...once I ultimately figured that out we started
going to their upstream AS's to get them yanked.
Fortunately these situations are relatively rare.
