RESTful Syndication allows you to automatically ingest content from other WordPress sites, using the WordPress REST API.
This can allow you to run a network of sites, which all receive the same post content.
There is a small selection of options, allowing you select the author, default post status, automatically create the appropriate terms, and set the Yoast No-Index status.

RESTful Content Syndication

Thank you so much! This plugin works. Kudos to the developers. I have been searching for forever for a plugin like this. Thank you so much.

Amazing!
