I probably should say this on the DNS mailing list but I find it quite curious that the study surveyed such limited stakeholders, and mainly the intellectual property crowd. "We gathered the data and inputs from stakeholders with two questionnaires: 1) the first one surveyed registries, registrars, hosting providers, other DNS operators, and 2) the second one surveyed intellectual property rightholders, practitioners, associations, business intelligence, and brand protection companies. The study also collected data from third parties and publicly available reports (secondary research), as well as evaluated the impact of DNS abuse." (Page 7) Intellectual property is not the best way to combat abuse and it will lead to protectionism and intellectual property overreach. Same applies to this space. They use "illegal" and "harmful" in their definition of DNS abuse which are ambiguous at best and expand the definition of DNS abuse so much that of course can result in concluding that we are all drowning in harmful activities online and it's all the DNS fault.

For those who are not following the DNS wg list:
The European Commission has published a quite comprehensive study on DNS abuse. (One could also call it enormous.)
It study itself be found here:

There is an additional document containing the appendix:

I have had a peak when waiting for other things to happen and it might be interesting read. Here is a gist from chapter Executive summary:
The study adopts the following definition of DNS abuse: Domain Name System (DNS) abuse is any activity that makes use of domain names or the DNS protocol to carry out harmful or illegal activity.
The main findings of the measurements are: a) In relative terms, new generic Top-Level Domains (new gTLDs), with an estimated market share of 6.6%, are the most abused group of TLDs (Appendix 1 – Technical Report, Section 5, p. 26). b) Not all new gTLDs suffer from DNS abuse to the same extent. The two most abused new gTLDs combined account for 41% of all abused new gTLD names (Appendix 1 – Technical Report, Section 9.2, p. 32). c) European Union country code TLDs (EU ccTLDs) are by far the least abused in absolute terms and relative to their overall market share (Appendix 1 – Technical Report, Section 5, p. 26). d) The vast majority of spam and botnet command-and-control domain names are maliciously registered (Appendix 1 – Technical Report, Section 10.3, p. 41). e) About 25% of phishing domain names and 41% of malware distribution domain names are presumably registered by legitimate users, but compromised at the hosting level (Appendix 1 – Technical Report, Section 10.3, p. 41). f) The top five most abused registrars account for 48% of all maliciously registered domain names (Appendix 1 – Technical Report, Section 11.2, pp. 43-44). g) Hosting providers with disproportionate concentrations of spam domains reach 3,000 abused domains per 10,000 registered domain names (Appendix 1 – Technical Report, Section 12.3, pp. 48-49). h) The overall level of DNS security extensions (DNSSEC) adoption remains low. (Appendix 1 – Technical Report, Section 15.3, pp. 62-63). i) There are 2.5 million open DNS resolvers worldwide that can be effectively used as amplifiers in distributed denial-of-service attacks (Appendix 1 – Technical Report, Section 16.4, p. 70).
The numbers above sound interesting.
