I think Cloudflare should make the bare minimum effort to kick services which are explicitly offering illegal DDoS attacks, given that their current policy of not doing anything unless legally compelled to is demonstrably enabling the overwhelming majority of DDoS providers to stay online, which has terrible optics when they're in the business of mitigating those attacks.

Whatever slippery slope excuses they give, somehow AWS, Azure, GCP, Fastly, Akamai and so on have managed to solve the impossible problem of turning away DDoS providers without imposing Orwellian censorship in the process.
