Instance admins can change literally any of that information in the database. There's a user whose account info says she's been on lemmy for a century.
You might be correct, although I would have expected the 4y ago part to not be a column in the database.
It would more likely have a CreatedAt column of type DateTime. Then using something like moment in the client you can format to show the date and time since, which makes it strange here that we seemingly have CreatedAt and TimeSinceCreation columns which is odd no?
Since June 13, 2023.
2023 / 13 * 6 produces a cool repeating pattern of 692307:
933.692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307692307
Counting from my first account almost 4 years, a bit over 3 year on this one
Longer than I thought. When I tried to register I was annoyed that the username was taken, but it turned out they also dropped the info in my password manager back in 2021!
16 June 2023 - my account appears newer than that because I switched instance.
I created my account last year but only started using it properly during the APIcalypse
July 26th 2020, a day that will live on in infamy as the first day of Hexbear.

I signed up to see what it was about during the Redditmageddon. I'm still on both sites and always will be though.
December of 2022. I was moving away from closed-source social media, and after Twitter -> Mastodon, Reddit was next. I didn't become active til the whole API thing tho, because Lemmy didn't have some communities that I liked. So I made one lol
