I tried both of my long-lived social media (Xanga, LJ, MySpace era) handles from my teen and early twenties years (I mostly use disposable handles now). I've deleted a decent chunk of those postings, but they were both recognized (top 25% on both), although for the wrong reasons (never a Minecraft Twitchstreamer, but I did have a Minecraft account with the handle name).
Really odd feeling to think that my writings from that period are helping these things. Not necessarily happy about it--I took that stuff down because it was so deeply personal, and a record of my life that didn't need to be public. Odd to think my teenage angst is, in some small way, writing the AI-generated e-mails I get now.
My wife tried it with her longest-running handle and it got social media right, but said she was on TikTok and Instagram (both wrong, just old Twitter). It's an interesting mix of truth and hallucination.
apparently i'm also a minecraft youtuber. i have never played minecraft or posted a youtube video.
i think somewhere along the lines the models might have just gotten "online handle" and "minecraft content creator" conflated.
