The response from Alibaba cloud:

Please provide as much information as possible when submitting an abuse report, including:

1. The nature of the alleged abuse or illegal activity.
2. The relevant law or regulation allegedly violated and the applicable jurisdiction where such law or regulation is in effect.
3. If the abuse report requests a party’s compliance with a particular law or regulation, it should set forth the basis for believing that party is subject to that law or regulation.
4. If a website is alleged to be the source of the abuse or illegal activity, the specific url(s) should be identified.
5. If a court, regulatory authority, or law enforcement agency has made a formal determination that abuse or illegal activity is taking place, that formal determination should be submitted if available.

Ugh.
