bypass of user level restrictions, a case of bug in 'Scribd.com'

http://www.youtube.com/watch?v=g-ETsFjRhqsFew weeks back, saw Scribd.com offering me to buy/upload something for downloading a Document uploaded on it. Second time when I opened some document, in another browser it shows disabled 'download', 'print', and 'mobile' option.

As I didn't get that Document to download, I didn't felt like reading it online also... so just thought why not try to download it and if I succeed, then I'll read it online.
And I read it online :)

So, here is a bug (which  has now been fixed) in Scribd.com... that allowed users to get a local copy of documents which were devoid of download and print options.

It's how layered limitation can be broken, and why restrictions must be implemented root-level-up and not just as user-level module.

How-To download the not-allowed ]
example: Bypass Scribd.com disabling Downloading/Print/Mobile on some links

Example Website Bug : a bug of Scribd.com (reported & got fixed) from aBionic@Vimeo

so, now you can either Print the document or create a PDF/image printing this document using softwares like PDFCreator.
