@bot @alex @lain @parker @graf @crunklord420 @mint @Moon there are potential "issues" with removing meta data that might affect 0.1% of people. E.g. a photography instance may wish to have a "remove metadata" option turned off.

But yes, it should be turned on by default. Removing meta data is pretty simple with exiftool (it can even be used to check mimetype (and get past the simple trick of changing the extension)).
