A previous answer stated:
For example, if you untick Life Events, they will never get displayed no matter what frequency you choose.
Wrong. I’ve unticked the Comments and Likes setting for everyone, but I keep getting those updates.
So-and-so "Likes" such-and-such… with an entire history of everyone who ever posted to some Facebook thread three times removed from me. I do not want to see "Likes." Does Facebook not work correctly or am I doing something wrong?
Click on the "Account" drop down menu (upper right hand corner of the page) then click "Account Settings" and go to the "Notifications" tab. Go through the list of notifications and deselect any notification you don't want. Fifteen out of the sixty-six notifications represented on this page are triggered by comments.
To opt-out of notifications for treads you're involved in, deselect the six notifications that start with: "Comments after me..."
same thing happened to me. this helps though:

On the Facebook wall,on the right hand of your recent activity you’ll find a button from where you get two options, to remove the post (nothing new) and “hide all friending activity” A popup window needs your confirmation. Also there you have a link to your profile story settings manager. You can access at any time this settings.
Same thing and with the “like” notifier. You can now hide all “like” activity. Actually, you have now a more flexibility in set the privacy options for almost all things what are posted on your Facebook wall. Test this settings yourself!
The profile story settings manager unfortunately is not easy to be find. You can spend time to take a look in any profile or account setting but you never find it. The link for this settings is placed at very bottom of your Facebook wall. Scroll down your wall, wait to load stories, scroll again and there you will find the link pointed in the previous screenshot.
Best Answer
There are many possibilities here:
You have not refreshed.
You are looking at the profile/wall of some friend of yours' whereas the setting only apply to your own News feed.
The posts that you see contains link to some "Page" which is "Sponsored".
The posts shouldn't show up but they are as they have received a lot of comments/likes from your friends and thus qualify as "Important" updates.
