Question 1: Your digital footprint can affect your future because if you post something disrespectful in the past it could haunt you. Ex One of my friends played basketball but his scholarship got cancelled cause of something he tweeted in the past. Another example is that woman who got fired after people found tweets about her. This can always affect you no matter where you work. In my opinion the digital footprint is sort of like karma. I say that because if you say stupid stuff in the past it will come back and kick you in the butt. This is one of reasons I will try to keep a good digital footprint
Question 2: The first way to keep it appropriate is to not post anything harmful or racist. #2 If it hurts someone don’t post it.#3 If it in any way can harm u in the future don’t post it.
Question 3: I Would tell them that if it could hurt you at any point in the future then don’t do it. Be smart about the things you state publicly
