It was not because of click fraud it was because I have a link on one of my mainstream sites to a website which sells wooden, samarai sword and other martial art swords
According to them its breaking thier Weapons TOS
"Weapon-related content
Google ads are not permitted to appear on sites that sell, facilitate or advocate the sales of weapons and weapon accessories. This includes but is not limited to the sales of ammunition, gun parts, hardware, pistols, rifles, BB guns, sporting guns, air guns, blow guns, and stun guns. This policy also prohibits the placement of ads on sites which sell explosives, including fireworks.
However, publishers are permitted to place Google ads on sites which discuss the sport of hunting. Also, Google ads may be placed on sites which sell paintball and airsoft guns. In the case of airsoft guns, U.S. law requires sites to have a disclaimer stating that airsoft guns are required to have the top of the barrel (.25") permanently colored in blaze orange."
I did not even know this was breaking thier TOS
