Frankly how is "he gained some size" anything but a neutral observation? If you read any negative connotations into it it's really your own prejudice. If the point is no one should comment anything on appearances you're really on the wrong site.
As for Hasan's body dysmorphia, I'd venture to say he wouldn't waste time on a forum full of bitter gay bitches, but even if he does he really doesn't need you fighting his battle. You being a white knight here reflects more your mental state than any noble virtue signaling. Take your own medicine and shut up your unwelcome opinion, I suggest you just ignore speech you don't like like I'm about to do yours.
