Akismet_REST_API::set_alert() – Update the current alert code and message by triggering a call to the Akismet server.
Akismet::sanitize_comment_as_submitted() – Ensure that we are loading expected scalar values from akismet_as_submitted commentmeta.
Akismet::set_form_js_async() – Mark akismet-frontend.js as deferred. Because nothing depends on it, it can run at any time after it’s loaded, and the browser won’t have to wait for it to load to continue parsing the rest of the page.
