However, it is the ISPs' customers who are the effective users of those IPs. Any complaint, whether reporting spam or botnet activity, can probably be handled more effectively by the people who run the systems connected to a given IP than the actual owner.
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. Best Ale --
