Can I enable CommentGuard only on ads and not on organic posts?

Yes. In your moderation settings you can apply automations only to ad comments. Organic comments will still show up in your dashboard and count toward your monthly limit, but CommentGuard will leave them untouched.

If you want organic comments completely out of CommentGuard, contact us. We can disable organic processing from our side. You can't switch this off yourself. Organic comments then won't appear in your dashboard and won't count toward your monthly limit.

To only change what you see (not what we process), use the Type filter in the dashboard. See How to show comments for posts or ads only?
