That's just me man. I've made friends with people in the hobby through arcade & pinball tournaments and gaming expos etc. that I didn't feel the need to hide behind an alias.
With YouTube, we were trying to portray me as the irresponsible father that spends all his time and money on video games and neglects the basic needs of his kids and always gets in trouble with his wife. Unfortunately, there were some people who didn't get the joke and thought that was real life.
I've actually heard reports of parents making "parody" videos about bad parenting on Facebook, with the kids rehearsing and acting the part of a troubled youth, then have the Child Protective Services called by some anonymous social justice warrior, only to learn the scenes in the alleged videos were entirely scripted for people's amusement. Nine times out of ten, by the time the authorities get called out, they are not amused to find it was all a joke, and in some cases the kids are removed from the home pending investigation.
I'm not saying you would ever carry things to those extremes, but parody videos with family have backfired before so I could see why you'd want that stuff gone. Imagine trying to explain the joke to church or PTA members. And a prospective boss would probably place the application in the circular file.
