Anyone with a YouTube or Google account can upload videos onto YouTube, as of 2015. When uploading videos, users need to follow certain community guidelines such as no uploading of pornography, violent or graphic content, hateful content, copyright violations, and threats.
Content that is considered to be harmful or dangerous, spam, misleading metadata or a scam is likewise prohibited. YouTube relies on its users to flag inappropriate content and anything that violates the community rules, so that the YouTube staff can review the videos and determine if they need to be removed or simply age-restricted. YouTube also penalizes the accounts of violators, and repeat offenders run the risk of losing their accounts and banned from opening any new accounts.
Though a majority of YouTube's content is uploaded by individuals, corporations and large organizations may also upload their own material as part of YouTube's partnership program. Though unregistered users can watch videos, only registered users may upload videos.
