That's what we are doing.
What about a mandatory abuse contact object and a DNS based list?

If the RIR is offering this service, why should it be mined. It would be
much easier to generate a daily rbldnsd file and offer it that way, than
offering bulk data and or an abuse finder API like RIPE is doing at the

To be honest, FBLs are not. FBLs are nice to tell a marketing company
they should unsubscribe the users, but the false positves rate is way to
high. Reports from Honeypots, real spamtrap hits, ssh attacks, sql
injection tries, phishing websites are much more reliable than a FBL
could ever be. Our customers do not even order FBLs for exactly the
false positives problem.

By the way, last week on huge anti spam summit in Barcelona, the biggest
issue was a to find a solution against outgoing spam and almost every
ISP was agreeing, that automatic abuse handling and direct escalation
would be the best way to get things done.

The more complaints you are receiving the easier it is to handle things
automatically. And the only thing you have to do at the end, decide
which reporter is how trustworthy and not clicking through a ticket
system all day long.
