Where can I complain about a domain or email that sends spam?

Question

Email

The domain is not disposable, but real. There is also a website. But it sends spam, hoping "what if the user becomes interested and agrees". The user himself did not subscribe anywhere.
Where to complain about a domain so that they are added to spammers? spamhouse after all, there are similar services. There?

Answer 1

It makes sense to write in Sportloto. There is no single service to deal with unwanted ones, train a spam filter, blacklist a domain, etc.

Answer 2

To the ECHR :) You can also go to the Vatican, to the Red Cross, to the International Organization for Assistance to Revolutionaries :)))
Put a spam filter :)
