Facebook not only knows a lot about you, but it also allows others to know even if you do not want to, you may remember. The privacy settings of the social network are so complicated, but they do not seem to work.
You know you can use a URL to view the whole record relationships, anyone you care about on Facebook? 
(For those you are not friends with, only the interactions that are available will be displayed public insurance, that is, for everyone.)
This URL takes advantage of the address faceboοk.com / us. In case you don't already know, this URL shows the entire Facebook history between you and the person you're in a relationship with. So with a quick tweak, you can customize it connection to two people.
Let's see how:
Go to the profile of the first person you want to see and note the name you see in the URL. Repeat the process for the second person you want to see.
In the address bar of your browser, enter the following address:
https://www.facebook.com/friendship/[όνομα-πρώτου-χρήστη]/[όνομα-δεύτερου-χρήστη]/
Replace Greek in the address with the names of the users you are interested in.
Press Enter.
You will see one σελίδα which will show all the posts, events, photos and videos in which the two people are tagged.
The tool it's a bit creepy, as if you use it right there aren't many secrets left on Facebook…
