Akismet_Admin::are_any_comments_waiting_to_be_checked() – Find out whether any comments in the Pending queue have not yet been checked by Akismet.
Akismet_Admin::erase_personal_data() – When a user requests that their personal data be removed, Akismet has a duty to discard any personal data we store outside of the comment itself. Right now, that is limited to the copy of the comment we store in the akismet_as_submitted commentmeta.
Akismet_Admin::exclude_commentmeta_from_export() – Some commentmeta isn’t useful in an export file. Suppress it (when supported).
Akismet_Admin::modify_plugin_description() – When Akismet is active, remove the "Activate Akismet" step from the plugin description.
