The Truth about High Paying Keywords

I've had a search through google help and there doesnt seem to be any information against using adsense with the keywords adsense in the domain.

However after reading through the TOS again, I'd like to make a bold assumption that 95% of sites out there which are succesful are somehow against adsense policy.

 

I prefer middle niche with high searcher than HPK but low visitor. just my 2 cent

 

I don´t believe it ...
