This is a nice feature, but it doesn't seem to be fully implemented. I disqualified all accepted submissions of one of my accounts18, but it still says it has 0.5 points.

Do you have a time estimate to when this feature will be available on other languages spojs?
Do you plan to allow problemsetters to do this to all submissions to their problems? Not just their own?

SET STATE (status column):

D - disqualify your submission (option is enabled if the contest setter checked an appropriate check box in edit contest menu, on the public SPOJ this option is enabled)
H - hide your submission: by checking this option you will hide your solution only in your own history, but this does not change the ranking and your subsmissions are still visible to others,
P - private submissions: this flag is enabled only for the problem-setters and only for their own problems, by checking this you will hide our submission to others (and won't be included in the global ranking)

is it ok?

disqualifying or (more general) changing the status of all submissions to his problem will be enabled for problem-setters soon.

I think there's a bug in this feature:

A problem setter can disqualify/ rejudge/ set score submissions of problems that he doesn't share the authorship.

This means a problem setter might manipulate any submissions even ones he has no responsibility. Actually, (Some) little evil Psetter(s) is toying with our online judge site and cause a lot of trouble and confusion to users. Hope that this problem will be fixed soon.

I also suggest that when a problem is disqualified or set to a fixed score, its owner should be notified of the execution and executor.

well, problemsetter can disq/set score of any submission on main contest,

that's ok!

@mima: it happens that some problem setters are intentionally disqualifying qualified submissions without saying anything in our site (vn.spoj.pl). As there is no logging file, we can't track who did that. It'd be better if problem setters can only disqualify submissions to his problems or the actions be reported.

disqualifying works as follows (or will work in a few days):

  • EB can disqalify any submission on spoj.pl
  • Contest Setter (eq. on vn.spoj.pl) can disqualify any submission on his own contest
  • Problem Setter can disqualify any submission on spoj.pl (only his own problems!)
  • user can disqualify only his own submissions

we will inform community in details in a few days,

REMEMBER: disqualifying is not a reversible operation!
