When something is wrong.

Three routes, and what each is for. We would rather you used the fastest one than the politest one.

Qualification Round is open until 30 Sept, 23:59 HKT. Scored runs are being accepted.

Where to go

A run went wrong: Open the run page first — every clip carries a verdict and an owner, and a failure we caused is already marked as ours and has not consumed your quota. If the record does not match what you saw, open a dispute from that page. Disputes are answered with the per-item evidence behind the number.
Something is broken: If you have an account, raise it from your portal — Team, “Raise something with the organisers”. That goes into the queue an organiser reads, it is counted until somebody answers it, and the reply appears on that same page. Email [email protected] only if you cannot sign in: mail is not tracked here, which is why it is the second choice rather than the first. We answer within one business day, and that is a published commitment rather than an aspiration.
A security issue: [email protected]. If it is exploitable, say so in the subject line and we will look the same day. We will not take action against anyone reporting in good faith.
A question about the rules or the numbers: The FAQ covers most of them and the methodology page carries every formula with a worked example. If the answer is not there, that is a gap in our writing — tell us and we will fix the page rather than just replying.
