Um, perhaps because you didn't explain the problem properly? :)
unfortunately you fail to understand the problem.
You never mentioned anything about being hacked before this. That's a completely different issue.
scammer pays nothing and earns money from the ad network by hacking into my website and adding his/her code.
At this point, your first priority should be locking down your website, finding out how and where your were hacked (and fixing that hole, as well as any others), and removing the hacked code.
You can talk to the police (best if you can show how much revenue you lost until you fixed the problem- shows that there's an actual loss of money involved). If the police decide not to go forward, you can talk to a lawyer about the issue. In either case, your chances for recovering money depend on your local laws, the location of the ad networks, the location of the hackers, and the willingness of your local police/lawyers.
