Tell HN: Uceprotect is extorting website owners

📝 Discussion Summary (Click to expand)

Theme 1 – Misuse of UCEPROTECT for broad traffic blocking
Many commenters argue that ISPs like Orange are improperly using the UCEPROTECT Level 3 list to block web/DNS traffic, causing collateral damage despite the list’s own warnings.
- “Orange's security filter seems to automatically block requests at the DNS level if your website's domain resolves to an IP listed on UCEPROTECT Level 3.” – goldenmember
- “The uceprotect Level 3 page clearly says using the list will cause collateral damage and should only use as an indicator … not to act purely on it.” – mrmattyboy
- “their lists are definitely used … I narrowed it down to this organization in particular blacklisting all of DO IP space.” – JohnMakin

Theme 2 – Debate over hosting‑provider responsibility vs. list legitimacy
Opinions split on whether being listed reflects a provider’s failure to curb spam or whether the list itself is an over‑broad, unfair punishment.
- “Hosting providers should be good citizens of the network and immediately terminate spammer accounts … I think this is a great policy decision by uceprotect.” – mmh0000
- “Why DigitalOcean in particular though? … they host spammers … it's a personal grudge.” – JohnMakin
- “Because they don't want to. You can create one too and add whoever you like to it.” – literalAardvark

Theme 3 – Skepticism about the reliability and potential abuse of reputation blocklists
Several users warn that such lists are informal, open to manipulation, and prone to scope creep, turning them into tools for censorship or extortion.
- “Spamhaus does not offer the ability to pay for removal. UCEPROTECT is uniquely evil in insisting on payment … Their revenue comes from unwitting victims.” – ttul
- “there is nothing preventing function/scope creep of these blocklists into things they should not be. Political bias, censorship, morality policing will trickle into blocklists.” – ButlerianJihad
- “Uce level 3 should never be used alone to block general tcp traffic.” – mercurialuser


🚀 Project Ideas

RBL Watchdog: Real-time IP Reputation Monitor & Alerting

Summary

  • Continuously checks your IPs and domains against UCEPROTECT, Spamhaus, and other RBLs, alerting you instantly when listed.
  • Provides a one‑click delisting request workflow and reputation score dashboard to reduce collateral blocking.

Details

Key Value
Target Audience SaaS operators, email senders, hosting providers, DevOps teams
Core Feature Real‑time RBL monitoring with automated alerting (email, SMS, webhook) and delisting assistance
Tech Stack Python/FastAPI backend, React frontend, PostgreSQL, Redis for caching, Prometheus/Grafana for metrics
Difficulty Medium
Monetization Revenue-ready: Subscription ($10 per monitored IP/month)

Notes

  • HN users complained that Orange blocks entire DO ASNs based solely on UCEPROTECT; this service would give them early warning and a path to delist before impact.
  • Provides concrete data for discussions with ISPs (e.g., showing that a listing is isolated and not reflective of actual spam volume), empowering users to argue against over‑broad blocking.

SafeSend SMTP Relay: Reputation‑aware Email Gateway

Summary

  • Acts as an SMTP relay that automatically routes outbound mail through IP pools with clean reputations, bypassing RBL‑based blocks.
  • Includes reputation scoring, warm‑up, and bounce handling to keep delivery rates high for legitimate mail.

Details

Key Value
Target Audience Developers, small businesses, indie makers sending transactional or marketing email
Core Feature Smart IP‑pool selection that avoids IPs listed on UCEPROTECT or other RBLs, with automatic failover
Tech Stack Go (SMTP server), PostgreSQL for IP reputation cache, Docker/Kubernetes for deployment, Prometheus for observability
Difficulty Medium
Monetization Revenue-ready: Usage‑based pricing ($0.10 per 1k emails)

Notes

  • Commenters noted that relying on a single IP (e.g., a DO droplet) can get you blacklisted; SafeSend lets you send mail without managing IP reputation yourself.
  • Provides a practical alternative to self‑hosted mail servers that are vulnerable to RBL over‑use, directly addressing the frustration expressed by users who had their sites blocked.

PolicyTuner: ISP Blacklist Weighting & Customization Plugin

Summary

  • Open‑source plugin for firewalls/routers (pfSense, MikroTik, OPNsense) that lets network admins adjust the weight, trust, and expiration of individual RBLs like UCEPROTECT.
  • Supports per‑list scoring, whitelisting, and detailed logging to prevent over‑broad blocking.

Details

Key Value
Target Audience Network administrators, ISPs, enterprise security teams
Core Feature Configurable RBL weighting engine that treats UCEPROTECT as a low‑confidence signal unless corroborated by other lists
Tech Stack C/iptables extension or Lua script for pfSense/MikroTik, SQLite for local config, Prometheus exporter for metrics
Difficulty Low
Monetization Hobby (open‑source, optional paid support/consulting)

Notes

  • Many HN replies pointed out that ISPs blindly enable UCEPROTECT, causing collateral damage; PolicyTuner lets them fine‑tune reliance on such lists.
  • Enables community‑driven best‑practice sharing (e.g., recommended weight values) and can be a talking point in net‑neutrality or spam‑filtering discussions.
