Quarivo Comment Shield

Activate it once. Quarivo Comment Shield quietly handles obvious spam.

Quarivo Comment Shield is a local, low-overhead comment spam filter built for site owners who want less notification noise without losing potentially important messages.

It combines several independent signals and never adds risk merely because of a comment’s language. Natural English and other multilingual messages are treated the same as Japanese comments.

A review inbox designed for real work

• Shows WordPress-stored moderation candidates at the top.
• Opens the full original comment, author details, score, reasons, and history in an accessible modal.
• Prioritizes unread, lower-confidence comments that may need human review.
• Searches by author, email address, IP address, or comment text.
• Filters by unread, needs-review, confirmed-spam, restored, and all states.
• Shows 25, 50, or 100 rows per page without loading the entire quarantine at once.
• Processes every matching result in small resumable batches, even when thousands are waiting.
• Allows deletion only after a record has been confirmed as spam or restored.

Quiet protection with safe defaults

• Stops high-confidence automated spam before it enters the normal WordPress comments table.
• Uses a honeypot, cache-safe form token, timing signals, duplicate/rate checks, link patterns, and content heuristics.
• Suppresses comment notification noise only for comments intercepted by the plugin.
• Works with standard WordPress comments and includes compatibility handling for common AJAX comment flows.
• Requires no account, API key, CAPTCHA, or external service.
• Aggregates equivalent repeated spam into one review record and places a finite ceiling on unreviewed quarantine growth.
• Falls back to WordPress moderation instead of losing a comment when quarantine capacity is unavailable.

Conservative local learning

When a moderator restores a false positive or confirms spam, the result is recorded locally. After enough consistent feedback, only soft signals may receive a small score adjustment. Strong security signals are never weakened automatically, and the maximum adjustment is capped.

“Publish and learn” can also allow the exact submitted email address. The plugin does not automatically trust a shared IP address or an entire email domain.

Privacy and retention

Quarantined comments remain on the site’s own database and are not sent to an external service. The plugin integrates with WordPress personal-data export and erasure tools.

Unreviewed quarantined comments are never removed automatically. Equivalent repeated submissions are grouped into one record, and a finite admission ceiling prevents unlimited growth. When capacity is unavailable, comments fall back to normal WordPress moderation. Confirmed-spam and restored records are removed after the administrator’s selected retention period (30 to 365 days). Action history is retained for up to one year.
