Because currently, it seems like the only thing it’s recording are downvotes. Meanwhile upvotes are completely ignored, leading to pretty much every profile I see having a negative reputation.
Also, I have a very fragile ego and my -6 reputation hurts a bit.
I think the best strategy would be to have a system that shows either both your number of up and down votes, or a ratio of them, rather than just the sum of them like Reddit (sort of) does.
I feel like it’d be a lot harder to fake a good ratio with an older account, than it would be to just manipulate a total score by exploiting lurkers by reposting generic content over and over.
