Sadly the only way of fixing it is making search results unattractive for cracking. Ranking of a page in search results is a metric, and every metric is a hackable metric. Only way they won't be hacked is if there's no incentive to. Sure a search engine that specialises on narrow area of knowledge without much money in it, can be very relevant and bullshit-free. But there's no way to make it work for the general web search. People hack things. If they didn't we'd have Communism built by now (yes the "good" - classless, stateless one).
