OP here, turns out its just another one of those bullshit curse things. Used Google Translate on my Android phone and took a pic. This is the rough translation:
"It should be noted that we have been programmed curse is applied as the viewer side as long as this video is not itadakanai continuous playback tens of hours. please choose your friends and share of always dozen people a video in order to remove the curse to completely."
So basically they're trying to make it seem like a curse that you need to spread to get rid of.
