Contact, corrections & content reports
The website, contest dataset and task dataset have separate maintainers. Use the corresponding link below with a page URL, a specific issue and public evidence for a correction.
Website and guides
Report broken website behavior, guide corrections, privacy questions or rights concerns about site material to the website repository. Identify the affected URL, what happened and the correction requested.
Public issues are not suitable for sensitive information. Start with a non-sensitive description and request an appropriate private channel when needed. No separate support email is currently published; do not send credentials to an unsolicited account claiming to be a maintainer.
Contest or public-task records
For contest dates, fees, eligibility or official links, send the contest repository supporting official evidence. Task states, sources and reward labels belong in the task-data repository. Registration, acceptance and payment questions belong with the official publisher.
A rights report should identify the page and material, its relationship to the original and available public evidence. An open-source repository does not clear every third-party asset; substantiated reports need assessment and correction.
