When users say "An error was shown" or "It's not working" but with no further details, I feel like they hate me.

Ask them where their brain went.

If you tolerate bad behavior, they will repeat it every time. If you don’t, they will repeat it somewhat less often.

If you're in a position to fuck around with them, you could reply non-reports with non-answers:

- An error was shown.
- That's normal behaviour when there's an error.

- It's not working.
- That may indicate there's a problem.

@electrineer stop stealing my techniques you bastard

Pretty common answer when they fuck up.
