Delete People You May Know ads on my facebook timeline Please PLEASE PLEASE HELP Ads are appearing and staying
Try an extension like Social Fixer or FB Purity - both of these have options that will allow you to remove those sections, in addition to making other tweaks to Facebook.
From what I read on other forums it is a feature you cannot turn off by default. You can only work around it e.g.
with an extension
using ad-block [which most people have installed anyway] and adding it's element to a custom block list (may take some tinkering)
there are also extension which allow you to hide certain elements in general
* These are just examples, I haven't tried any of them.
