Hey it is not a bug it automaticly gives you one vote bcuz i think that might cause error if the save had zero votes (Correct me if i am wrong this was just a guess)
I think @Rajat is correct, that was true at some point a while back.
Today, 0 vote saves work fine, but we still give the automatic one vote. This won't go away, because it makes it less likely for a save to have negative votes, and negative total votes is kind of a morale killer.
Yeah, @Rajat and @jacob1 are right, when I first joined, I thought that it gives you automatically an upvote so you can't downvote on your own saves, because, guys, who'd do this? This is probably wrong because it makes almost no sense, lol
