An update on residential proxies and the scraper situation

Original Article ↗ Hacker News Discussion ↗

Residential proxy networks and aggressive web scrapers are overwhelming many independent websites, as traffic once dominated by search engines and archives is increasingly driven by data-hungry AI and poorly written crawlers. Commenters debate what, if anything, should be made illegal, how little control end-users have when apps quietly turn their devices into proxy nodes, and how hard it is to block abuse without locking out legitimate readers—especially when bots hide behind residential IPs and ignore robots.txt. Proposed responses range from proof‑of‑work gates, shared datasets like Common Crawl, and micropayments to stronger app‑store policing and network‑level monitoring, but there is no consensus on a solution that preserves both an open web and site operators’ ability to stay online.

Residential proxies & legality

  • Many see residential proxies as “botnets in plain sight”: SDKs in free apps, VPNs, and media boxes quietly turn user devices into exit nodes.
  • Dispute over legality: some argue it’s not clearly illegal without explicit bans on such SDKs; others say there’s no informed consent and it should be treated as malware-like.
  • Debate over whether app‑store bans (e.g., on SDKs like NetNut’s) are legitimate security measures or monopoly abuse.

Scraping intensity and impact

  • Core complaint: massive, poorly behaved scraping overwhelms sites, especially dynamic endpoints (search, diffs, paginated lists), effectively acting as DDoS.
  • Residential proxies plus rapid IP rotation make IP‑based blocking ineffective and risk collateral damage to innocent users.
  • Some think this is largely driven by AI training demand; others argue it looks more like generic or even malicious traffic, not rational data collection.

Shared crawls and data access

  • Several propose “better Common Crawl” or per‑site downloadable archives/ZIPs so scrapers don’t need to hammer sites.
  • Counterpoint: projects that already publish full free dumps (Wikipedia, OpenStreetMap, etc.) are still heavily scraped; many bots ignore these channels.
  • Common Crawl contributors note datasets are large but accessible, with indices and recrawl logic; usage is meaningful but not ubiquitous.

Poisoning and data quality

  • A community actively tries to “poison” scraper/LLM training data.
  • Critics say this is mostly symbolic: the web is already noisy, and straightforward filtering and cross‑checking can largely neutralize such efforts.

Mitigations: PoW, captchas, and paywalls

  • Proof‑of‑work systems (e.g., Anubis) are seen by some as the least-bad defense, preferable to captchas and compatible with stateless HTTP.
  • Others report usability problems, privacy concerns, and argue PoW doesn’t scale: attackers can run optimized native code or leverage botnets; browsers are at a disadvantage.
  • Ideas surfaced: HTTP 402 with per‑request payments (possibly via Lightning), karma/identity‑based rate tiers, or site‑wide micropayments. Skepticism centers on friction, economics, and regulation.

Open web tensions

  • Fear that anti‑scraping measures will hurt the open web, block benign crawlers/archivers, and entrench dominant players (Google, Cloudflare).
  • Some praise residential proxies as tools to access data behind corporate walls; others call them an untrustworthy scourge undermining small sites.

Operational tactics & local defenses

  • Operators discuss firewalls, blacklist sharing, fail2ban‑like setups, and traffic monitoring on home routers to spot compromised IoT devices.
  • IP‑range blocking works better in IPv6 by blocking larger prefixes, but widespread CGNAT and proxy churn complicate attribution and fairness.
