Legal

Acceptable use.

One rule, stated plainly: do not use Comlumen to break the law or harm people.

Effective 5 September 2026

The policy

Using our platform for anything illegal is a violation of our terms of service and will result in immediate deplatforming — removal of the offending sites, revocation of access, and closure of the account — and referral to law enforcement partners where required or applicable.

The same applies to conduct that harms people or the platform itself: malware, phishing, deception, harassment, and attempts to probe or disrupt the service are treated the same way, whether done by hand or by an automated agent.

Reporting

To report a site or listing that breaks this policy, write to support@stacklumen.com. To report a security vulnerability, write to support@stacklumen.com — we thank people who report responsibly.

These pages are written to be read, and they are the terms we operate by — but they are maintained by the team, not issued as legal advice. If something here matters to a decision you are making, ask your own counsel, and if anything looks wrong or unclear, tell us at support@stacklumen.com.
