As many of you know that Facebook patched one of my latest exploits where i was able to tag users in non removable posts, you can read about it in this article : http://shar.es/1oXPXy
It seems that Facebook failed patching the vulnerability, somehow they placed a wrong code where it coverted the menu line choice with another facebook page .
When a friend tag you in a post, you can simply click the right top arrow to choose to untag, unfollow, hide all .. etc .
Facebook patching mistake converted the "Hide all from .." menu line to be " Hide all from Ahmed Spider احمد سبايدر", where "Ahmed Spider" is a facebook page.
How to check !
Copy this demo link : http://shar.es/1oXPXy
Create A new post , Type @ and tag one of your friends .
Hit enter for a new line after the tagged user line, paste the above link and wait for facebook to preview your link .
Now your friend will see " Hide all from Ahmed Spider احمد سبايدر" as the above picture shows .
Bug reported, should to be patched correctly soon .
