It seems that the below picture with some code [4:0] is wide-spreading all over facebook.


@[4:0] Mark Zuckerberg

If you try and type @[4:0] in any comment box in facebook, the name “Mark Zuckerberg” will appear.

You can find out in here:

It seems that the first number “4” in “Mark Zuckerberg” case, is the facebook profile ID, however it seems that the 2nd number is useless, or at least I’m still unable to figure it out.

If you know what the second number is for, please leave a comment and let us know 🙂
