Comment spam drains moderation time

Link farms, fake reviews, and promotional spam fill comment sections at scale. Even with moderation queues, someone has to review and delete each one — and high volumes of spam degrade your site's signal-to-noise ratio for real users.

KireiFilter scores each submission the moment it arrives. You can auto-reject high-confidence spam, hold borderline posts for review, and let genuine content through — no manual triage needed for the clear cases.

Use the score to build a moderation pipeline

0.0 – 0.3
Auto-approve

High confidence it's legitimate. Publish immediately.

0.3 – 0.6
Hold for review

Borderline — store but flag for a human to check.

0.6 – 1.0
Auto-reject

High confidence it's spam. Return an error and discard.

Node.js example

comments.js
const res = await fetch('https://kireifilter.net/api/v1/spam-check', {
method: 'POST',
headers: { 'Authorization': `Bearer ${process.env.KIREIFILTER_TOKEN}`,
'Content-Type': 'application/json' },
body: JSON.stringify({ content: req.body.comment, ipAddress: req.ip, email: req.body.email }),
});
const { score } = await res.json();
if (score >= 0.6) return res.status(422).json({ error: 'Spam detected' });
if (score >= 0.3) return db.comments.create({ ...req.body, status: 'pending' });
db.comments.create({ ...req.body, status: 'approved' });

Cut moderation time. Keep good comments.
