Sure but in those situations most like the CoC's like we are talking about (things like the contributor covenant) would not be need to remove the person that was abusive

I have been a part of many projects with out these types of CoC's where people have been removed from the project because they were an asshole, or the project is forked and the assholes are left behind

Historically that was the way of open source.

Today however it is much different... Politics and Social Status seem to matter more than Code, merit, and reality
