-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.

-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No

-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior,  harassment of an

-# Federation in WordPress
-
-The WordPress plugin largely follows ActivityPub's server-to-server specification, but makes use of some non-standard extensions, some of which are required to interact with the plugin. Most of these extensions are for the purpose of compatibility with other, sometimes very restrictive networks, such as Mastodon.
-

-
-## ActivityPub
-
-### HTTP Signatures
-
-In order to authenticate activities, Mastodon relies on HTTP Signatures, signing every `POST` and `GET` request to other ActivityPub implementations on behalf of the user authoring an activity (for `POST` requests) or an actor representing the Mastodon server itself (for most `GET` requests).
-
-Mastodon requires all `POST` requests to be signed, and MAY require `GET` requests to be signed, depending on the configuration of the Mastodon server.
-
-More information on HTTP Signatures, as well as examples, can be found here: https://docs.joinmastodon.org/spec/security/#http

 1. The blog-wide profile is only compatible with sites with rewrite rules enabled. If your site does not have rewrite rules enabled, the author-specific profiles may still work.
-1. Many single-author blogs have chosen to turn off or redirect their author profile pages, usually via an SEO plugin like Yoast or Rank Math. This is usually done to avoid duplicate content with your blog’s home page. If your author page has been deactivated in this way, then ActivityPub author profiles won’t work for you. Instead, you can turn your author profile page back on, and then use the option in your SEO plugin to noindex the author page. This will still resolve duplicate content issues with search engines and will enable ActivityPub author profiles to work.

 1. Once ActivityPub is installed, *only new posts going forward* will be available in the fediverse. Likewise, even if you’ve been using ActivityPub for a while, anyone who follows your site, will only see new posts you publish from that moment on. They will never see previously-published posts in their Home feed. This process is very similar to subscribing to a newsletter. If you subscribe to a newsletter, you will only receive future emails, but not the old archived ones. With ActivityPub, if someone follows your site, they will only receive new blog posts you publish from then on.

-    *   Please **setup a local environment** instead whenever possible. Most of our code is open source (see above).
-    *   If that's not possible, **limit any data access/modification** to the bare minimum necessary to reproduce a PoC.
-    *   **_Don't_ automate form submissions!** That's very annoying for us, because it adds extra work for the volunteers who manage those systems, and reduces the signal/noise ratio in our communication channels.

 1. The blog-wide profile is only compatible with sites with rewrite rules enabled. If your site does not have rewrite rules enabled, the author-specific profiles may still work.
-1. Many single-author blogs have chosen to turn off or redirect their author profile pages, usually via an SEO plugin like Yoast or Rank Math. This is usually done to avoid duplicate content with your blog’s home page. If your author page has been deactivated in this way, then ActivityPub author profiles won’t work for you. Instead, you can turn your author profile page back on, and then use the option in your SEO plugin to noindex the author page. This will still resolve duplicate content issues with search engines and will enable ActivityPub author profiles to work.

 1. Once ActivityPub is installed, *only new posts going forward* will be available in the fediverse. Likewise, even if you’ve been using ActivityPub for a while, anyone who follows your site, will only see new posts you publish from that moment on. They will never see previously-published posts in their Home feed. This process is very similar to subscribing to a newsletter. If you subscribe to a newsletter, you will only receive future emails, but not the old archived ones. With ActivityPub, if someone follows your site, they will only receive new blog posts you publish from then on.
 
 So what’s the process?
