That can be complicated. Most metadata viewers only delete data from default locations. You might be surprised at the things that show up in proprietary locations when you read a graphics file with a text editor. If I ever need to take a picture with zero info in it that can be linked to me, it's going to be pretty low-res because I'll be using a very old camera. For normal uses and security levels appropriate for everything that happens on this board, that level of paranoia is not justified. Thank goodness.
