I actually thought Censys (and others like Shodan) were already blocked?
Maybe they changed IP ranges. If so, blocking hosts like this may be a concern for IPs/hosts/ASN reaching us now or in the future.
(Although I don't agree, because when I use such sites, I notice data on my hosts are missing. Nonetheless, I understand it takes bandwidth from AMPRGW and others.)
