Does Facebook acknowledge screenshots that are taken on an IPhone?

If you screenshot an image on Facebook on an IPhone, is it acknowledged on facebooks system as in when you screenshot do the people who run Facebook know it or is it just you who knows? Because with snapchat when you screenshot it is acknowledged

Nope Facebook Does Not Tell People Who Has Screenshot What

  • Top button of iPhone 5 does not work. Is there another way to take screenshots? Is there a app or something else to help take screenshots on my iPhone 5 after my screenshot button has messed up?
  • No Matter what i do Itunes will not acknowledge my iphone? I've completely restarted my phone, re installed iTunes, checked the cord pins, used different USB ports what the hell is wrong why will my iPhone 5 not get recognized on iTunes. I don't understand the problem i restarted the whole Apple communicating whatever too. Iv'e done anything any website could tell me so if someone knows that would be awesome.
  • My macbook won't acknowledge my iPhone? It has recognised my iPhone 5 before hand, and this is the only connector cord that I can use before anybody suggests that. No pc or laptop will acknowledge it but the cord isn't broken because when I plug it into the wall it works perfectly fine.
  • My iphone is taken over by facebook I tried to post something to facebook from free my apps and now i'm stuck on facebook. I can still move around and navigate through facebook and do stuff on it but the home and power buttons won't do anything and i can't shut it down or anything. What is going on! (iphone 4)
