Having run one of these in the past, when take-downs of C&Cs was still semi-useful, my ethos on this is problematic, however, I am as of yet undecided as to this one. An AS-based reputation system for all sorts of badness:
In my opinion, third-party security based AS-reputation systems will eventually become de-facto border filtering systems for ISPs, but that day is still not here, as that is still socially unacceptable in our circles, and will remain so until it becomes _necessary_.
Regardless of my musings of Operators World cultural future, this systems seems rather interesting, and no doubt you'd want to take a look at your listing.

We tried to outline some of the challenges of building such a system in our NANOG52 presentation: http://www.merit.edu/networkresearch/papers/pdf/2011/NANOG52_reputation-nano... In particular see slide 4. where we tried to lay down what we think the requirements are for a socially acceptable reputation system. With a bit of luck we might be able to announce the release of our system before the next NANOG mtg, but in my opinion collating host reputation reports is just a small and the easiest part of the effort. The key is in solving the challenges of allowing (and incentivizing) participation and being robust to false information injection. Comments are welcome. Thanks. -manish
