i felt that we should be very careful of what we post because all the informations can be shared by the public. Just like the video, the girl posted some informations of hers online and soon some people which she doesn't know recgonise her. Before get to delete it away others can save and edit whatever they want.So, it is dangerous to be posting any informations of ourselves.Even if we try to delete it away, some data may not be cleared ,hence, it will be troublesome to totally get rid of it. We could place some information like fake names or nicknames, fake age, fake address and our sub mail accounts thats okay to show the public. If we really want to show others our personal information, there should be still a limit and try not to give especially real phone numbers, address etcetera.
