Valine is deprecated since hexo-component-inferno 4.2.0. LeanCloud, where Valine stores the comments, shuts down on January 12, 2027, after which this demo stops working. Besides, Valine exposes the stored comments to anyone with the site's public App ID and App Key: the commenters' email addresses are always exposed, and their IP addresses are exposed as well if record_ip is true (ppoffice/hexo-theme-icarus#788). Please do not leave your email address in the comments below, and use Waline, Twikoo, or another comment system for your own site.
