I guess you need traffic to make money with AdSense
Than the best traffic for you would be from Search Engines (SE).
- So if you have good content, you have to keep it fresh... so update atleast once per week.
- Do link exchange and submit to directories
- do some SEO - That is important for SERP
- Put URL to your site to your SIG and post in forums and comment in blogs

I think you shouldnt be banned for using pay per click site...
Problem is where you link to and not where link comes from...
