What are 支持 for?

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

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

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