I look at it differently, even if someone isn’t going around posting racist/horrible things, people and tastes change over time. I’ve been a part of fandoms that are now seen as cringey or toxic. I’ve also grown up more as a person and I look back at a lot of my old comments as sophomoric. I write differently, and my opinions on things have changed as well. I’ve had people dig through my post history on sites like Reddit to try and find a “gotcha” based on some remark I made years ago.

All in all, I personally feel like it is a good thing to cycle through usernames throughout life.
