There needs to be more information here to provide clues for folks to respond, but it looks like something that you did in the procedure of removing elements of content from you site could have caused this.
Two things I'd be watching for ; one is how your link architecture has been effected, and two, duplicate content - but really i don't have enough to go on.

I have got Adsense ads in it, but google blocked my site from account because mature related content. My site has never been any adult oriented conntent, but i did mention it was little forum pages which i have removed instantly.
Furthermore, i have removed forum pages compeltely from my site to avoid any user activity.
Site block was June 1st, traffic remained normal, but before 10 days only 1/5; I am still ranking high for many keywords. I have many google images referals
You have any idea? Does Adsense remove cause traffic drop?
