I remember reading that when national parks tried to make a ‘bear-proof’ trashcan, they found that there was a larger overlap between the smartest bear and the stupidest human to make a viable product.
I feel like it’s a similar situation here. The smartest kid and the stupidest adult are far more similar than we’d like to admit.
I don’t think there is a “dead giveaway”. Plenty of kids can pass as adults online and plenty of adults seem like kids online. And sometimes with stuff like word usage/grammar/etc you can’t tell if it’s a child or someone who doesn’t speak English very well or maybe an English-speaking adult who happens to type like that. There’s a lot of different people in the world.
I imagine that part of it comes down to motivation. I pretended to be an adult on a special-interest forum when I was twelve years old because I needed an escape from my miserable existence. At that time, I had no control over my life and every morning I woke up meant I had a new chance for traumatic shit to happen. I desperately needed to be someone else, so I took my time, researched shit, and avoided any conversation where I might be outed. I’m sure I didn’t fool everyone, but I got some shocked responses when I went back as an adult and owned up to it.
Kids doing it for the authority boost or just as a childish fancy will be easier to spot. Kids doing it as a coping mechanism for their horrible lives will probably blend in a lot better.
Damn. I know this life. I don’t wish it on anyone, except those who exposed me to it…
