It is worth pointing out that Wesley specifically avoiding dumping data from the S3 buckets which were directly related to User Data / Information. "There were quite a few S3 buckets dedicated to storing users' Instagram images, both pre and post processing. Since the Faceboook Whitehat rules state that researchers need to "make a good faith effort to avoid privacy violations", I avoided downloading any content from those buckets" In fact, the only 'sensitive data' he retrieved in regards to user account information were the weak employee logins.

Is gathering up the credentials of employees not also a privacy violation? At this point you're going way beyond proving that you have access to something - you're actively trying to probe and see how deep the rabbit hole goes. I don't (personally) believe that this is acceptable behaviour under a white hat program.

I see your point but I'm not sure if having passwords like 'changeme' qualifies as being a privacy violation... You should almost expect it to happen at that point.

But I do recognize that cracking passwords goes a step too far.

Fair enough, I can only say that it seems like they could be more explicit on that point, but I don't see anybody arguing against the idea that that their rules could use clarification.
