Hello,
In accordance with CoC's amendment policy https://www.mediawiki.org/wiki/Code_of_Conduct/Amendments. The committee proposes an amendment on behalf of one of the community members to be added in unacceptable behavior section https://www.mediawiki.org/wiki/Code_of_Conduct#Unacceptable_behavior:
Soliciting help, support or technical assistance for websites whose predominant activity or content is behaviour that explicitly and significantly violates provisions of the code of conduct is forbidden in Wikimedia technical spaces. For example, websites advocating violence or hate speech are not welcome to ask for support on Wikimedia support forums.
This is similar to w:en:Wikipedia:No Nazis https://en.wikipedia.org/wiki/en:Wikipedia:No%20Nazis
This will be open for three months for community feedback in https://www.mediawiki.org/wiki/Topic:Xgg6dvg2athdb1h7 and if the community reaches consensus and the committee won't oppose it, It will be added to the policy. Best Amir (he/him), On behalf of the CoC committee
