"Polarik" was the screen name of Ronald J. Polland, Ph.D. He is a lying sack of shit.

Even before Loren outed him, we knew two things about Polarik that suggested he's no document expert:

1. He didn't know about "Ducky," the Adobe JPEG APP12 tag used when "Save For Web" setting is used in Adobe Photoshop.
2. He didn't know that UV light, a humidifier, and a sauna aren't the correct way to "season" (prematurely age) a document so it looks like it's been in a file cabinet for 47 years.

Whoever he is, he's no document expert, and that's for sure.
