Although the Internet has not been created for anonymity, many users posting comments on blogs hope that they will remain anonymous. The article presents an attack on revealing the e-mail addresses of users posting comments on the sample website using Gravatar. This attack aims to make readers aware of the fact that by posting comments on sites using Gravatara services, we are exposed to the disclosure of our e-mail addresses and sometimes even of our real identity.Keywords: Gravatar, deanonimization, e-mail, MD5 hash function
