I guess to kick this off I'll start with one of my own stories
So whenever I was twelve and discovered that you could lie about your age on the internet, I made an account on Neopets proclaiming that I was 76 years old (totally believable, guys.) At the time, I was still subscribed to the Neopets magazine, which came with some custom fonts for the neoboards. So I was thinking "O THIS IS KEWL!!!" and copied a really girly pink looking font from it.
I got on the Neopet boards (on the help board, god knows why) and posted an obnoxious board that read:
"HEY DUS MY FONT LUK CUTE?!?!"
Some people were nice about it, but most had answers like:
"lol you suck at signature making"
Needless to say, my twelve-year-old seventy-six-year-old self was upset. I remember getting off that board crying and deciding I hated everyone on the internet.
