Posting Links

Posting links may be another way of making extra money on the web. A site that I found (actually a shorten your url site) pays you for sight views. Posting links that are able to get page views could be a nice way to gain some extra money on the web. Post links everywhere is what they suggest however the rules are totally against spamming. Is there a way of posting links and making extra money on the web? Is it worth a look?
