I suppose there are two sorts of errors:

System errors: falsely attributing you with certain penalties (or credits). The workaround here is the same as with a bank - provide a statement and a mechanism to dispute entries.

Fine errors: penalising you when you don't deserve it. This is like anything else in the justice system, although it has the advantage that it should be an accumulation of a larger number of smaller inputs (positive and negative), so individual errors should act like noise and remain negligible.
