Oh lord. And yet again we have people without enough technical expertise commenting on things outside their knowledge. I am seeing this more and more lately. People in my field are labeling themselves "experts" and in fact are completely clueless.
There is NOTHING here that proves the document is a fraud. Of course, it VERY EASILY could also be fake. There is NO document out there that I can't create a fake digital image of.
The "proof" in the videos is just plain laughable. To start with, he needs to open the file in Acrobat itself first and see what elements are defined. Photoshop will "translate" a pdf when importing it and you have already introduced new data at that point, thereby invalidating everything you do from then on. I can explain this further if anyone cares, but the basic gist is that the document may be fake or it may be real... without a paper copy to validate, no one can say for certain... but this "proof" that it's fake is not at all valid.
