describing to them about the exploit with a link to facebook post that i made to Sarah Goodin's timeline
Sarah Goodin is the girl that was in the same college with Mark Zuckerberg .
this picture shows the post .
facebook security replay was that the link gives error opening , if course they didnt use their authority to view sarah's privacy posts as sarah share her timeline posts with her friends only , i was able to view that post cause i'am the one who did post it even i'am not in her friend list . that what i told them in a replay and i also told them i may post to Mark Zuckerberg timelime as this picture shows :
as usual they ignored my replay so i did report another , this email shows their replay to my second report including the report :
Hi Ḱhalil,
I am sorry this is not a bug.
Thanks,

of course you may cant see the link because sarah's timeline friends posts shares only with her friends , you need to be a friend of her to see that post or you can use your own authority .
this is a picture shows that post :

-----End Original Message to Facebook-----i told them that sarah shares her timeline with her friends only as i also sent them a picture shows the post i made to sarah's time line , their replay was " sorry this is not a bug " , so i replay back and i said that i has no choice than to post to Mark Zuckerberg's timeline .
so i did post post to Mark Zuckerberg's timeline , as those pictures shows :
i told him about the exploit and all the report i sent with a link to the last report including facebook security replay , minutes after a facebook security engineer Ola Okelola comment on my picture on facebook asking me to send him all the details about the exploite :
you can see the conversation on this link : https://www.facebook.com/10151865722018885
a minute after that i got my account disabled ,as they said facebook has all the right to disable any facebook account without any reason given , i made another report asking facebook security to reactivate my account , this is the email shows my report including their replay :
Dear Khalil,
Facebook disabled your account as a precaution. When we discovered your activity we did not fully know what was happening.Unfortunately your report to our Whitehat system did not have enough technical information for us to take action on it. We cannot respond to reports which do not contain enough detail to allow us to reproduce an issue. When you submit reports in the future, we ask you to please include enough detail to repeat your actions.
We are unfortunately not able to pay you for this vulnerability because your actions violated our Terms of Service. We do hope, however, that you continue to work with us to find vulnerabilities in the site.
We have now re-enabled your Facebook account.
