whois中的“blocked_word:CG”是什么意思?

一位顾客说他们想和我们一起停放一个域名。 理论上,他们应该已经注册了这个域名。 但是当我用whois来查看时,我得到这个:

 jcastro@localhost:~$ whois notactuallythedomaininquestion.br % Copyright (c) Nic.br % The use of the data below is only permitted as described in % full by the terms of use at https://registro.br/termo/en.html , % being prohibited its distribution, commercialization or % reproduction, in particular, to use it for advertising or % any similar purpose. % 2017-11-07 09:26:29 (BRST -02:00) % blocked_word: CG % Security and mail abuse issues should also be addressed to % cert.br, http://www.cert.br/ , respectivelly to [email protected] % and [email protected] % % whois.registro.br accepts only direct match queries. Types % of queries are: domain (.br), registrant (tax ID), ticket, % provider, contact handle (ID), CIDR block, IP and ASN. 

这是什么意思? 一个真正不存在的域不会给我那个blocked_word行,而是给出:

 jcastro@localhost:~$ whois randomwordsalad.br . . . % No match for randomwordsalad.br . . . 

两者之间的区别在于,带有“被封锁的词”的WHOIS输出的名称不能被注册,而具有“不匹配”的名称可以被注册,尽pipe没有被注册。
