I lost almost 110 ratings without even submitting any accepted solution in November Lunchtime. I participated very late so just try submitting one question but it result in a runtime error so I left the contest, still they reduced my rating. Can anyone help with this? @admin
I think since you submitted during the contest time, irrespective of whether you got a WA/RE/TLE Verdict, you will be considered as having taken part in the contest and hence the rating drop.
