I think lots of agencies strip the exif, but there's no requirement that they do it. If there's information in there you don't want the world to see, you would need to remove it prior to uploading rather than hoping every agency does it for you.

You have mind of confused me, so I was leaving this alone.

What does the EXIF have to do with the size or the license? If you are asking, do the agencies always remove the EXIF, NO they don't. AT least one used to and not says they will leave it. I never searched for my images to see if they include or have that data removed, in licensed use.

It's also possible that on the agency sites, it doesn't show, but when someone pays for a download, they get it. The buyer could be removing the data... So it's pretty complicated.

Not a problem at all, I try to read things a few times to see if I can figure out the intent. 

No they don't always remove EXIF, some do some don't. Some that did before, don't anymore. (at least last report was DT was leaving it with files now, I don't know for sure) Some end users remove it.

No answer for sure which isn't helpful very much. Sorry.
