I have a mix of .co.uk, .com, .net, .org, .biz, .uk, .be and .eu domains.
All of which are subject as domains to ICANN and/or governmental registry rules.
Surely it's the provider of the hosting who gets blacklisted not the 'name' of the host.
No, not so much. It takes some work to determine the "hosting" of any particular machine, and it really isn't appropriate to blacklist a hoster (i.e. an Autonomous System Number with multiple large address assignments) for the behavior of one customer, provided they address policy violations in a sensible fashion and are not ONLY hosting abusive customers.
A DNS parent (like a registry or pseudo-registry) is a much simpler target to identify and a much more granular way to target consequences. For example, Postfix has directives to reject mail based on the name or IP address of the nameserver used for the sender domain, the HELO/EHLO name, and the (verified) reverse client hostname. It has no way to reject based on ASN.
