Thanks Denis. abuse-c arity is a point I was dubious about.

Thus, it is not currently possible to publish an abuse-c with the customer 
address and keep the ISP copied at the same time, as desired.
In order to know what is being sent thete, the ISP needs to provide its own 
address and (if appropriate) forward complaints received there to the customer.

This bit is possible. The ROLE object containing the "abuse-mailbox:"
can be maintained by the end user so they can set their own email
address and change it whenever they wish.

This bit is not possible. The "abuse-c:" attribute is 'single'. So the
resource object can only ever reference one abuse contact.

I'm not an expert on all the supported RIPE db details, but I think you
could have an abuse contact object, that you could modify, with the
main resource linking to your abuse contact plus the ISP one.

I find that abuse contacts are fairly static ones (if not directly
following rfc2142), so the client need to write to it is probably not a
very relevant use case. Maybe some weird setup, such as if you wanted
to present a dynamic abuse contact that changed every day-

In a considerable amount of cases, the ISP's customer is also the spammer. I 
would prefer not to talk to them when complaining about their behavior - in the 
best case, they will ignore me, in the worst case, they might do something in 
revenge.



That makes sense when you're reporting spam.  Botnet activity differs.  If RDAP 
data allows to recognize which abuse contact belongs to which kind of operator, 
tools can accept options to output either one or both.



The IP owner is the one who can pull the plug on misbehaving customers. As it 
is much easier to identify IP owners, I can collect reputation data about who I 
can trust to handle my abuse complaint responsibly, who will just ignore it, 
who will forward it unedited to their customer. Depending on this assessment of 
their trustworthiness, I will or won't report.



Wow!  I just collect those which bounce.  Some send some feedback, and in a 
minority of those cases I seem to be able to grasp that they actually do 
something to mitigate reported abuse.



There are very few cases where reporting to end users makes much sense. Either 
they operate their system responsibly including monitoring the mail rejects and 
bounces, then they already know there's something that needs to be fixed, or 
they don't, and most often don't care, and my complaint will probably not 
change that.



Some operators say they refuse abuse reporting by email because they want 
complainants to fill web forms.  Of course, web forms have fields that provide 
for better handling.  However, the only handling I can think of is to associate 
the IP field to the corresponding customer and automatically forward the 
complaint there.  That could be done by RDAP.

When you say " irrespective of the  resource holder, based on the wish
of its customer" do you mean without their consent or control? That is
not possible as they maintain the assignment object. I would also say
it is not desirable. That would allow an abuser to override the
resource holders abuse-c and ignore all abuse reports.



Yes, I meant extra attributes linked to the assignment object.  If it's not 
possible let's just forget it.




And, if yes, would it be acceptable by the resource holder or are there
contractual impediments? Finally, if feasibility is ok, would operators
take advantage of it or is it only me? >

If you are talking about adding extra abuse addresses to assignment
objects by agreement with the resource holder, as I explained, that is
possible now by simply adding an abuse-c to the assignment .



Except that I don't have write access to the assignment object.
