It might just be a small issue because I noticed it's not all profiles, 'cuz I checked mine. (or it's just my computer I can never really tell.)
I've actually never used imgur before, but I will attempt to put it up. :)

It's like that because of the dot lines he has. If you'll notice the box goes out to the end of the lines, that's because he has no spaces. This is nothing wrong with the site, he just needs to space his profile out.
