I doubt it will hurt it particularly much, it is after all only crappy CAM quality, where some one used a video camera or smartphone, to record it from a movie theater screen. It would had been worse if it had been a screener, where some one actually managed to get their hands on a DVD or Blu-ray for review purposes and spread that one on the internet.
persen1, i guarantee you that within a week from now there will be a VERY good new cam copy of this movie online (before it's American release at least).
