Batch Comment Spam Deletion

Modifies the Empty Spam action in WordPress to process the spam deletion in batches instead of all at once.

Flector

The plugin sends you an email each time a comment goes to the spam folder. The plugin will come in handy in combination with anti-spam plugins like <a href="https://wordpress.org/plugins/antispam-bee/" rel="ugc">Antispam Bee</a>, <a href="https://wordpress.org/plugins/invisible-captcha/" rel="ugc">Invisible Captcha</a> and others that completely filter out comments from bots. It saves you the trouble of having to visit the “Spam” folder and manually check whether any real comments have been marked as spam by mistake.
We don’t recommend installing this plugin if you use <a href="https://wordpress.org/plugins/akismet/" rel="ugc">Akismet</a> only – you’ll be drowned in hundreds of emails every day.

Spam Notifier

The plugin sends an email message when a comment goes to the spam folder.
