Spotted a thing. Apparently you can't recreate the thing in a thread's op, so I will be doubleposting once this is posted to attempt recreation. If it doesn't recreate,
this is the post I saw with the thing, and if it looks normal to other people, I see this:

tl;dr it appears that if someone does the /me emote at the start of the post, it doesn't actually show you their picture and other profile information, which ends up looking kinda odd. As title says, unsure if bug or feature.
:edit: ok, apparently the forums won't let you do the /me thing in tube's circus, so I can't actually recreate it in here, if I try posting with /me at the start it just tells me permission denied
