But the issue here is if I can identify an individual spammer who is causing me problems who should I contact to try to have this person/organisation disconnected?
The answer is; you should contact someone who has committed to receive and act upon reports of network abuse. RIPE can get involved by requiring its LIRs to maintain an abuse desk that commits to receive and act upon abuse reports. Beyond this RIPE can publish the contact details for any 3rd parties who have committed to receive and act upon abuse reports.
This brings us back to the question of how to enforce a policy that says everyone should keep their contact details up to date. I know it is a difficult question, but until it is addressed the whole policy on abuse handling fails.
You are right that this is the key question. "Everyone" does not have a contractual relationship with RIPE therefore RIPE policies do not apply to "Everyone". This is unlikely to change. In any case, it is a waste of time directing abuse reports at "Everyone" because, chances are, "Everyone" has not made a commitment to receive and act upon abuse reports. Some might say; but "Everyone" should make such a commitment. That is a noble sentiment and one which often drives politicians to make laws. If you really believe in this sentiment then RIPE is the wrong place to discuss it because RIPE members are not politicians and RIPE has no input into national or EU laws. --Michael Dillon
