I decided I would compare the image in several ways..
First, I looked at the quality and lettering of the images.
1. The lettering seems exact but that doesn't prove anything..
2. I noticed in one of your images (the photo in which you seemed to have clicked on this person.. showing their info?) that the friend icon-report-trade buttons were unclickable.. this only occurs when you click on yourself
You cannot prove much since you could of simply removed this person from your friend list and you could have also said something and then moved away as soon as you pressed enter..
