+ * Fired when the plugin is uninstalled.

+ * When populating this file, consider the following flow
+ * of control:
+ *
+ * - This method should be static
+ * - Check if the `$_REQUEST` content actually is the plugin name
+ * - Run an admin referrer check to make sure it goes through authentication
+ * - Verify the output of `$_GET` makes sense
+ * - Repeat with other user roles. Best directly by using the links/query string parameters.
+ * - Repeat things for multisite. Once for a single site in the network, once sitewide.
