In Phaver, everyone can see which mail Phaved each other. I value this idea because hiding this feature will bring personal privacy. Also, since Phaver users see the number of likes on posts, they refrain from Phaving posts with high number of likes to save points. If the number of likes and Phaves received by the posts in the feed are hidden, I think users will use Phaver more beautifully and in accordance with its purpose.
