Voted for These votes are unnecessary, superfluous..
There's a dust threshold of 2 cents, if a post or comment doesn't reach this amount then all the votes on that post are wasted. So if you have no stake voting is pointless. All it does it add more transactions to the chain, but it is just like throwing turd on the turd pile.
Unless you have like hundreds+ of SP there is no point in voting at the current price, you won't earn anything from it. Build your account up first by posting quality content, or buy some SP. Then you will be making a difference.
