Sketchy Facebook contact pages

So Facebook has generally been pretty safe for me recovery wise, but recently insanely sketchy contact pages have been popping up as suggestions in my contact feed (strip clubs, porn sites, etc). I was wondering if anyone else was having this problem and if so is there a way to turn off the contact page function?

Facebook or any social media such as Instagram Contains mild porn and Relapses are mostly caused by social media, It is smartness to stay away from it.
