Pretty common, for example when using databases as a mostly dumb store with all the logic in application code, and then a second application (or big refactor) appears and they introduce a subtle bug that results in an invalid `INSERT` (or whatever), and the database happily accepts it instead of rejecting it.
This is actually my preferred approach. If you want to put a 4gb base64 as your phone number, go right on ahead; best believe I will truncate it to a sensible length before I store it, but sure. Who am I to question your reality.
Sadly, people abuse shit like that to pass messages (like naming Spotify playlists with messages to loved/friends/colleagues while in jail) and maybe we have to assert a tiny bit of sanity on the world.
