Facebook arata adresele IP ale utilizatorilor

Facebook are un sistem de notificare, care te informează prin e-mail despre diverse evenimente care par interesante pentru proprietarul contului facebook.
Acest sistem de notificare are unele neajunsuri, datorită lui se poate afla IP adresa persoanei care a generat evenimentul.
Drept exemplu mai jos prezint mesajul în totalitate cu toate header-ele a unui e-mail real de notificare, care l-am primit prin e-mail, despre faptul că Iulian Carauş a comentat la statutul Elenei Chiriac. Şi urmează să vă lămuresc, cum de utilizat e-mail-ul de notificare pentru a afla adresa IP a lui Iulian Carauş.

Acest cod se poate obţine la Yahoo! făcând click dreapta pe e-mail-ul de notificare şi selectînd View Full Headers.

Iată mesajul de notificare
