wondering any idea how to disable somesite advertise in google adsense ? becuase some website appear not to be match with my website contents
You can use the competitive ad filters. However you must keep in mind that Google takes some time before it can match ads with new content. Also if you keep blocking sites just because the ads are irrelevant, you may end up blocking the higher paying ads.
Yeah, you can prevent some sites from appearing in adsense ads on your sites using competitive ads filter in Adsense CP.
