The comment points hook awards points to a user when they leave a comment on a post.
The comment points hook lets you choose a post type in addition to the number of points to award. (This feature was added in version 1.5.0.) To award points for comments on any points type, select “Any”. To award points only for comments on a specific post type, like Pages, select it in the list. If you would like to award points for comments on multiple types of posts, use multiple instances of this points hook.
The points for a comment will be awarded when the comment is first approved. Since version 1.9.0, the points will be automatically deleted if the comment is removed (marked as spam, moved to the trash, etc.). If the comment is approved again after this, the points will be awarded to the user again.
