I disliked ACC as a teen because I had a bad anxiety problem and wanted my username changed because I was "in the closet" in real life but out of the closet with some of my ACC friends and my username was known by my family. I told the mods why I wanted it changed after they asked for details but they ended up telling me it's impossible to change it, if that was true then they shouldn't have asked me in the first place
And to make things worse a few weeks later I got a user ticket (in a thread for saying I liked someones town name) at that point I was already upset with the staff so I spoke up publicly in the thread saying I was disappointed about how unnecessarily strict the staff is, then a mod who I never spoke to decides to post in the public thread saying "You should be happy you didn't get a banned for talking about inappropriate content with a mod"
Needless to say I was triggered. I was exposed by a staff member publicly, the secret I tried to keep at the time was shared between mods apparently and I also felt the mods were being unfair towards me for giving me tickets for such petty things.
I ended up getting over it and I still use the website because I made a lot of friends there and at the time half of the mods were just teachers pet children so you can't really expect them to know any better.
And sorry for bumping an old thread but funny story, I still want want my username, this thread popped up when I googled change animalcrossigncommunity username. Lol
