What are pujian for?

its for something anda did and they liked so they give anda those as unspendable points

If anda really like someone's photo, answer, pick, quiz, link etc. anda give them a prop for it.

^also just to randomly give them a prop because anda either like them atau wanna talk to them on their blog/homepage so instead of sending them an actual message anda just put it on their blog along with a prop. lol...
