Facebook not only knows a lot about you, but it also lets others know even if you don't want to? The settings The privacy of a social network is so complex, but it does not seem to work.
Did you know that you can use a URL to view the entire relationship history of anyone you care about on Facebook? 
(For those you are not friends with, only the interactions that are publicly available will be displayed, ie for everyone.)
This URL takes advantage of the address faceboοk.com / us. In case you did not already know, this URL displays the entire Facebook history between you and the person you are in a relationship with. So with a quick tweak, you can customize this 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 the proletterof tours you use, 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 be presented with a page showing all posts, events, the photos and the videos in which the two people are tagged.
The tool is a bit creepy, as if you use it correctly there are not many secrets left on Facebook…
