No, you can’t. Your instance will go down, but all your posts and comments will still live in read-only mode on the instances they been federated before.

In mastodon (another activity pub service) you can export your account with subscriptions, but not the posts. So, if it’ll happen, you gotta start from scratch.

I like vscode. Even after paying for intellij, I find it’s look, which is much cleaner, and speed, which is far more better than intellij’s.

Use neovim then (if you don’t like vscodium). It can be configured as IDE, but its hard to remember all keybindings.
