Lesson 3: Be careful what you upload to the internet.

If you want to post something on the internet, make sure that it is not anything bad, since anything can be traced back to you. Good ninjas would never post anything mean about someone else of a group of people, but instead post only nice things. In the future, people will check your account, and if it has many mean comments or posts, then they will most likely not want to be friends with you.
