You, you can add that list. Motherfuckers will let you type a password as long as you wish, only to internally truncate it. Was driving me crazy until I tried to log in on the mobile app, where it does prevent you to type more characters…
Not even that. I’m getting serious Usenet vibes (from the early 90s, not the thing it has since devolved into). Even the decentralized paradigm with independent servers syncing with each other is conceptually similar (although I’d bet NNTP was a quite different protocol than what we’re using now).
OTOH, if you build a playlist manager for playlists everyone can add to, you make sure nothing anyone adds will break it…
