This is the second time today that I got one of those mails telling me, the dear facebook user, that "due to Facebook policy changes, all Facebook users must submit a new, updated account agreement, regardless of their original account start date. Accounts that do not submit the updated account agreement by the deadline will have restricted." To execute the update, they ask me to "unzip the attached file and run 'agreement.exe' by double-clicking it".
The mail was sent, miraculously, from the mail account on which I recieved it. At least that is what they gave as sender mail address. So, here's my piece of advice for you in case you get one of those mails, too:
Do not, repeat: NOT! open the zip file and do not, repeat: NOT! repeat: NOT EVER! run agreement.exe on your computer. If the facebook team wants to contact you, no matter what their request may be, they have other ways of communication, they have other technical ways of updating the account agreement and sure as hell will not pass your own mail address off as theirs!
Now I do know that many of you will not really need that piece of advice - but there are enough people who would not double-check before opening that file. So please spread word to prevent as many cases of harm as possible, ok? Thanks!
