According to a post that is currently making its way around Facebook, you can check that your Facebook account has not been hacked by entering ‘@[4:0]’ into a comment.
The message claims that, if the comment changes to display the name Mark Zuckerberg, it means that ‘your fb hasn’t been hacked’.
Entering the code ‘@[4:0]’ into a Facebook comment from a mobile device will indeed display the name of Facebook CEO Mark Zuckerberg. However, the appearance of the name is certainly not an indication that your account has not been ‘hacked’. In fact, the appearance of the name has nothing whatsoever to do with Facebook hacking or lack thereof.
Here is what is really happening. Every Facebook profile has a unique identification number. Entering the number and code in the way described in the message displays the name of the Facebook user with that identification number. And ‘4’ happens to be Mark Zuckerberg’s unique identification number. Almost any combination of numbers in the format @[string_of_digits:0] will display a name corresponding to the user with that ID number.
Being a Facebook founder, Mark Zuckerberg was obviously one of the first to create an account on Facebook, as indicated by his low ID number of 4. Entering ‘@[5:0]’ displays the name of Facebook co-founder Chris Hughes. The first three numbers don’t appear to belong to any users and may have been initial test accounts.
This message is a reworked version of an earlier viral post that claimed that adding a Facebook comment with the last three digits of your phone number in the format @[three digits:0] would miraculously display your cell phone’s name. But, the name displayed was not that of your phone, but that of an early Facebook user with a three-digit ID number.
So, in short, this is a fun little Facebook trick to show your friends, but it has nothing to do with hacking.
Note that, while the trick works when using Facebook on a mobile phone, it will usually not work on a desktop or laptop computer.
Go onto a photo on Facebook and type in the comments
If it changes to Mark Zuckerberg it means your fb hasn’t been hacked. Mark Zuckerberg is the creator of fb…..
Importance NoticeAfter considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.
These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.
Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.
And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.
When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.
I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.
A Big Thank YouI would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.
I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.
Closing DateHoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.
Thank you, one and all!
