Submission Requirements & Community Rules
1. Submission Requirements
- Registration: email verification required; usernames may use Chinese, letters, digits and underscores (2–20 chars); CAPTCHA required after 3 consecutive failed logins; sessions last 30 days by default.
- Acceptable content: research papers, technical reports, popular-science long reads, essays and opinions; experiments or hypotheses are not mandatory — unverified papers must clearly state “unreviewed / not peer-reviewed”; plagiarism, infringement, illegal or politically sensitive content, ad spam and filler are not accepted.
- Format: single file ≤2MB (frontend hint + backend enforcement); PDF upload, online preview and multi-format download; the body uses a safe Markdown subset.
- Permissions: anonymous users may only browse/download; registered users may submit, edit their own papers and favorite; admins may edit/takedown/delete any entry and ban accounts.
2. Community Rules
- Content: original-first; citations must credit sources and data should be traceable; reprints or republication must credit the original author and source; illegal content, political sensitivity, infringement, ad spam, harassment and flamebait are forbidden.
- Authors: one account per person; list all co-authors for collaborations; creating alt accounts to boost likes or favorites is prohibited.
- Moderation: normal submissions publish immediately with an audit trail; admins may review and takedown at any time; matches in the profanity filter are auto-flagged for manual review.
- Enforcement (escalating): first a warning with a fix deadline → on repeat, takedown → for severe or repeated violations, account ban → IP ban.
- Copyright & license: authors retain copyright; the platform only holds a display/distribution license; each paper carries a default license notice (e.g. CC BY / display only).
- Authorization & submission: authors and reprinters/partners should agree on scope and usage in advance; the platform encourages authors to self-submit (their own work); third-party unauthorized posting or republishing is not supported.
- Originality certification: authors may apply for National Time Service Center (NTSC) timestamp certification to generate authoritative, tamper-evident time proof. Certification via this site is not recommended (costlier, not worth it) — please certify directly with the NTSC yourself and attach the certificate / proof link to the paper or submission note. To optionally support the site, you may tip on Aifadian (link on the homepage).
3. Notice & Disclaimer
This site only stores the upload time record and does not provide or undertake timestamp notarization (upload timestamps carry no notarization effect); the site will not tamper with upload timestamps, but it does not guarantee academic standing (no endorsement, no academic qualification), unless formal notarization is separately completed.
