Also my account was disabled because of invalid clicks which
i have never caused or told somone to do it for me so I have been
trying to figure out where invalid clicks would come from.
And I have finally know the reason why it was disabled after a
thorough investigation.

The reason is that there may be thousands of computer using one
single
IP that is shown to outside world when they connect to the internet
from their wireless internet connection that this network company
sold
to its customers in my country.

My website content is related to travel and tourism and where I live
is a small island and there are many residents from all over the
world
and they look for hotel, car hire or related information using their
internet connection which was bought from the same network company to
find
a place to stay for their relatives..etc

I have explained that to Google Adsense Team many times, and their
reply was that "how ever I was disappointed with their decision they
would not reactive my account..."

I wrote to Google Adsense Team the 4th times but had no result.

How do you deal with a similar situation as mine?
