Answer:
Because adults or older people look down on minors/kids due to the fact that they are younger then them and they see them as weak and all of the above. So due to that when a minor needs affection or support in general form time to time they may act fake or put a fake face on. So for example you may see minor who made a channel like TommyInnit, Ran boo, and Tubbo they didn't get help starting there channels now tommy has 11 millions followers, Tubbo has 2 million followers, and has more on streaming site, same with Ranboo he has 2 million and much much more on twitch. So, thats a little message for any minors to never give up.
