I had one image rejected on Istock for "This file contains legible information such as names, signatures, license plates, phone numbers, identification numbers, etc. Due to concerns relating to privacy and related property rights, we cannot accept this file unless this information is removed, or a release is obtained" . They even attached a problematic section of the image, here it is

So where you see something legible in there? The picture is of a wooden sauna interior, blank wood without anything written on it, even the wooden handle has no any prints or anything. Apparently the guys know something about my own sauna that I don't. (oh and no, I'm not rich, I'm just living in sauna country)
