YSK That if you delete your lemmy account, your comments/posts made on other instances will remain there forever.
So say I make an account on lemmy.world and post a bunch of stupid comments around other instances then decide to delete my account because I'm ashamed of them. After I delete my account, a copy of all those comments I made on other instances remain on those instances as a "shadow copy." There isn't any way to actually delete them all. The copies of the comments/posts on your home instance will be deleted
tldr:
Don't say stupid shit on other instances you'll regret later! They never leave that instance!
Why YSK: so you can think carefully about what to comment and post.
