Frequently asked questions

Will it wrongly reject real comments?

Genuine comments are approved and anything uncertain is held, not deleted — so worst case a real comment waits for a quick manual approval.

Can I whitelist regulars?

Yes. Check the commenter's email against an approved list and auto-publish known good contributors without AI review.
