Features

The feature list from the plugin's own readme on WordPress.org, trimmed to the essentials.

  • An explainable score with three zones. Every rule can be switched off or reweighted, and the breakdown is shown for each decision
  • Observation mode for the first seven days: everything is recorded, nothing is blocked, so you see what would have happened before you arm it
  • A log with a release button, so a false positive costs one click instead of a customer
  • A learning filter trained by your own moderation, entirely on your server
  • Quarantine for form submissions: the log keeps the submitted values and releases them per row
  • Comment quarantine in the native WordPress spam folder, with a column that shows the score
  • A dashboard widget with the last 14 days, the totals for 7 and 30 days and a breakdown per channel
  • Statistics and a CSV export of the log for your own records
  • Move-in help: reads what a previously installed anti-spam plugin had configured, shows what maps across, and imports it on your confirmation. Nothing is…
  • Your own keyword list, and the option to remove the XML-RPC methods for comments and pingbacks
  • Invisible to visitors. No captcha, no puzzle, no cookie
  • Fail-open by design: if the plugin hits an internal error, the submission passes through to normal moderation instead of vanishing
