Firstly I'd like to apologize for my earlier tone, espcially to KingBroly it was out of order on my behalf, so sorry.
Secondly, With how hungry Smash fans could be, it's not really surprising this has become the mess it has, lots of people dig for this info, and because others know they want it, it spreads like wild fire amongst friends.
Think about it, this could've simply started with one guy, who sent some stuff to one or two others, and now it's been let loose as it is now, in what ... 5 or so days? even if it hadn't gone viral, I bet the pictures would've been in the hands of at least 50-100 people by now.
I say chances are this was gonna happen regardless of who actually did it.
