Hi, I am a BH seo newbie. I set up a wordpress site with tens of thousands of posts last week. There's no any BH techniques done on the site. I just hired a social bookmarking service to get about 100 backlinks. After two or three days of the social bookmarking service, google indexed my site and I got about 200-300 visitors a day from google. I use site:mysite.com to check and found about 2000+ pages are indexed in google. I then put some adsense on every page of the site. Then I start to see googlemedia bot coming in. It's normal. However, today, I get almost no visitor. I check site:mysite.com again and found only my homepage there. (It was 2000+ indexed page yesterday!) Am I penalized by google? de-indexed or sandboxed? possible reason?
