I and some other maintainers highly suspect that this content is AI-generated. While we can't be 100% sure, we also don't think the additions meet our editorial conventions and quality standards anyway. In particular, you almost never see us using entire bolded paragraphs, because you should be writing in full sentences instead. In addition this should be living under "Examples". Could you at least cite the sources for the guidelines you wrote here? |
