TBH, reading that just kinda made me feel bad for the kid. The only thing he did that was objectively shitty was him pocketing charity stream money to buy a new PC. He did give that money back, tho. But other than that.
He lied about his age (said he was 18, although he was 14/15). He met this girl in chat and started an online relationship with her, but they never met. She sent pictures, but he never did, because he was supposedly fat or ugly or something. Then she shows up at his house and he's too embarrassed to meet her, so he gets his gramma to lie to that girl and tell her he's not home. Then she finds a picture of him online and gets pissed, so she airs her grievances with him publicly. Eventually, he gets the boot from vinesauce.
He sounds like a dumb kid doing really dumb kid things on the internet. I was also a dumb young adult on the internet once, so I can kinda relate. Thankfully, I never acquired internet fame lol.
Anyway, it's probably for the best he got booted. Hopefully, he learned something.
