Ask HN: How do I make UK and US hosters disown Russian Firewall?

I have some traffic going in and out on private TLS-enabled ports, including to Russia. I have noticed persistent attempts to connect to my endpoints. I've not shared these endpoints to anyone and they're not on standard ports. So the only option is Russia's GFW knockoff is picking up host/port pairs from traffic and trying to abuse these. The thing is, they are using UK/US address space to do so, specifically:

UK's driftnet.io and datacamp.co.uk

US's Shadow Server Foundation / Hurricane Electric in Bay Area

I believe it is not only immoral to aid state censorship but also illegal for these companies to provide address blocks/ hosting to Russia's agencies.

So my question, where can one complain regarding illegal activity / sanctions evasion to make these companies disown Russian Firewall / RKN?
