ACCEPTABLE USE

Private does not mean consequence-free.

These rules protect people, the Plexus network, and the ability to keep offering encrypted mail.

Effective 16 September 2026

Do not use Plexus to

  • Send unsolicited bulk messages, spam, scams, phishing, deceptive promotions, or fraudulent requests.
  • Distribute malware, destructive code, stolen credentials, or instructions intended to compromise systems or accounts.
  • Threaten, harass, stalk, exploit, extort, impersonate, or deliberately endanger another person.
  • Create, solicit, possess, or distribute illegal content, including child sexual abuse material or non-consensual intimate imagery.
  • Violate intellectual-property, privacy, publicity, confidentiality, or other legal rights.
  • Probe, disrupt, overload, bypass limits, automate account creation, scrape identities, or interfere with Plexus or another user’s device.
  • Evade a suspension, facilitate prohibited conduct, or use Plexus in violation of applicable law.

Reporting and blocking

Recipients can block a sender locally. A recipient may also submit a safety report, which deliberately shares the reported subject and message excerpt with Plexus administrators for review. Do not misuse reporting tools or knowingly submit false reports.

How we respond

Depending on severity and available evidence, Plexus may warn, rate-limit, block delivery, preserve relevant records, restrict or terminate an account, or make a legally required report. Immediate action may be taken to address credible threats, active attacks, child safety risks, or serious unlawful conduct. Encryption may limit what Plexus can independently inspect.

Appeals and questions

If you believe action was taken in error, email [email protected] with your handle, the decision you are appealing, and relevant context. Do not include recovery codes, passkeys, or unnecessary sensitive information.
