In the same situation, I whine about wasted n reputation points,
or say that another n points / votes down the drain.
These "lost" points are wasted, as in a wasted opportunity.
Or wasted, as in youth is wasted on the young:
something given but not used to its potential, and therefore lost.
These "lost" points went down the drain,
as in money down the drain,
that could have been yours and surely useful for something,
but now it's gone, irrecoverable.
In short, the word for these "lost" rep points to me is "wasted".
We're looking for an expression that meets two conditions at the same time:
- Indicate that rep points were lost
- Indicate (or at least imply) that the loss is due to excess upvotes, as opposed to serial upvote reversal
I think "wasted" comes close enough.
It indicates that something was lost.
To me, "wasted" may imply that the loss was at least partly my fault.
When I receive too many upvotes,
it's usually because I answered too many questions during the day.
A fewer would have been enough, my effort is partly wasted, so it's partly my fault.
On the other hand, loss due to serial upvote reversal is out of my control.
Those rep points are taken away from me by external factors, through no fault of my own.
The word "waste" doesn't seem to fit this case well,
so it naturally suggests the other likely alternative,
that I'm receiving upvotes in excess of the daily cap.
As a side note,
perhaps as a little consolation,
these wasted reputation points down the drain are not always 100% lost.
in the fortunately rare event of serial upvote reversals,
those "lost" points seem to mitigate the damage.
