You have an "Artist" EXIF tag that says "RUBEN SAFIR". It is present in
the "Before" image. That one if from the camera. If you T3 is like my
70D, somewhere in your "wrench icon" settings, there is a "Copyright
information" entry where this can be set.

The orientation problem is weird:

With my Gimp and my Canon Camera, just scaling a vertical image and
re-exporting:

Before:

 * Camera Orientation              : Rotate 270 CW
 * Orientation                     : Rotate 270 CW

After:

 * Camera Orientation              : Unknown (255)
 * Orientation                     : Horizontal (normal)

While on yours:

Before:

 * Camera Orientation              : Rotate 270 CW
 * Orientation                     : Rotate 270 CW

After

 * Camera Orientation              : Unknown (98)
 * Orientation                     : Rotate 270 CW

So 1) the "undefined" tag is different and 2) the second Orientation tag
is  not reset. Since you are using Linux it could be a problem with the
exif library (libgexiv2.so.2.0.0 and libexiv2.so.14.0.0 on my system)
