I found a guy who said his adsense account was banned by google. Most probably it was suspended due to invalid clicks. So never click your ads. But what should you do when this happened? Dont bother contacting google. You are wrong, and they will not change their decision.
You can still monetize you website/blog using other advertising company. Here are some that I recommend:
- Adbrite
- Bidvertiser
- Text-link-ads.com
- Linkadage
