Stop WordPress comment spam without a CAPTCHA
The worst comment spam is not the obvious junk. It is the polite, on-topic sounding comment with a link buried at the end. QWeb Spam Shield reads each comment for intent, so the link-droppers that slip past blocklists get caught.
Why comment spam keeps getting through
Akismet judges comments largely on reputation, so a steady trickle of well-written link drops gets through. Those are the dangerous ones: they look human, they add SEO-killing links to your pages, and some accounts exist only to inject scripts later.
How Spam Shield stops comment spam
- AI reads the comment and flags the promotional pattern even when the wording sounds natural.
- Link and reputation checks catch link stuffing and known-bad sources.
- Anonymous comments with empty author fields are checked, not skipped.
- Held for moderation, so a real comment is never deleted by mistake.
A quiet moderation queue
No CAPTCHA is added to your comment form, so real readers comment freely. The bots get scored and held, and your moderation queue goes quiet.
