How Do You Stop Facebook From Posting on your wall?

[Brian]

How Do You Stop Facebook from Posting on your wall, and I mean FACEBOOK putting ads, for apps and games or telling me what other friends are playing. I do not care and I am fed up with all the posts by FACEBOOK. I have already blocked all games in the security section but FACEBOOK insists on trying to get me to play them.
Thanks. Done ALL the usual stuff in the security section and enlarged the screen so I don't see anything on the right hand side. But now FACEBOOK is actually posting on my wall with stuff I can't edit or erase. I guess FACEBOOK is in control. I still have the option to quit I suppose.
