So, how do Reputation Points work? Because I'm a little confused how I'm at -5. Is that system still under construction?

@jcrm No. KBin has 2 positive interactions - upvote & boost. Boosts impact your rep positively, upvotes do nothing. But there's only one negative interaction - downvote, which does impact your rep negatively. Until we flip the mental switch, I expect a lot of people will have negative rep.
