Is your feature request related to a problem?

Just tried the brand new comment feature (V0.16.0), I am not able to add a comment without log in.

Is it by design?

Describe the solution you'd like

possible to support adding comment from anonymous visitor? I'm thinking to use memos as blog.

如果后期要开发游客评论，最好配套对应的审核系统，例如必须先审核后发布，或者当内容中存在链接进行审核等，以保证不被广告或者垃圾信息侵扰。

If you want to develop tourist reviews later, it is best to have a corresponding review system. For example, you must review before publishing, or review when there are links in the content, etc., to ensure that you are not intruded by advertisements or spam.
