Cory – Blocking Countries because of scrapers

What the title says, Cory is blocking countries due to misbehaved scrapers. We do a bit of this at work, blocking misbehaving countries when they flood our sites with traffic. There is very little reason that anyone should be visiting the website of a city unless they live in the city, maybe the city next door, and maybe the originating country of the city.

99% of the time when a site gets DDOSed by something it’s coming from somewhere outside the country. The leading countries are India, China and North Korea. Sure a single person, or a family could be researching a city, but that doesn’t explain the traffic floods.

Many of our customers use Cloudflare so we just block them at the Cloudflare level and call it a day. I go back after a few weeks and remove the block because some valid traffic is reasonable.

I had to take a line like that on my own site as well, block a bunch of offending scrapers and bots from countries. It sucks to stop regular people from visiting my site but I’ve already dealt with a bill of $5k in a month that should have been $50 and I don’t need another one.

I've checked on #YaCy from time to time because the project seemed very interesting but the resources (disk space and memory) too big for it to be run on cheap hardware as a hobby. I don't know of any other #OpenSource (optionally) #distributed #searchEngine with #webCrawler included (independent of Google and co., unlike metasearch engines).
I thought maybe somebody will rewrite it in Rust or something, but no luck so far. There was an announcement of significant optimisations made once, but the resources needed seem to be huge still.
Sadly, the focus nowadays seems to be on adding #AI to it. I guess I'll wait until the bubble is gone. 😕

Is there a standard hostname/domain to use in the documentation for a web spider? Ideally the host/domain should exist, have multiple webpages, and be OK with random traffic from people testing the web spider example code.

The New Leaf Journal became inaccessable for about 1-2 minutes this morning. Fortunately, I opened the site almost immediately when it happened. I opened my server logs and found what was probably the offending bot/scraper so I could block it. I kept the server logs open to watch for any other questionable activity. I saw an interesting user-agent string.

My two sites are often crawled by Mastodon servers and Fediverse-related crawlers because both sites function as ActivityPub servers (you can follow this account on the Fediverse at @naferrell@social.emcafe.org). I had not previously seen the crawler GodHatesMastodon, but I understand through the grapevine that there are some questionable instances out there. Fortunately, there is no reason for anyone to hate The New Leaf Journal. As my friend and colleague Victor V. Gurbo once explained, “The New Leaf Journal is a family website.”

#Firecrawl, an #opensource #webcrawler for #developers and #AIagents, raised $14.5 million in a Series A round led by Nexus Venture Partners. The company, which is already profitable, plans to use the funds to expand its team and develop tools to help website owners get paid when AI uses their content. https://techcrunch.com/2025/08/19/ai-crawler-firecrawl-raises-14-5m-is-still-looking-to-hire-agents-as-employees/?Pirates.BZ #Pirates #Tech #Startup #News

Cloudflare sperrt den Perplexity-Bot.

Perplexity AI przyłapane na gorącym uczynku. Firma miała potajemnie omijać blokady stron

Firma Cloudflare, gigant w dziedzinie bezpieczeństwa i infrastruktury internetowej, opublikowała raport oskarżający popularną wyszukiwarkę AI, Perplexity, o stosowanie nieetycznych praktyk.

Według dochodzenia, Perplexity miało używać potajemnych, niezadeklarowanych crawlerów do pobierania treści ze stron internetowych, które wyraźnie zablokowały dostęp dla botów tej firmy.

Dochodzenie Cloudflare zostało wszczęte po skargach od klientów, którzy zauważyli, że Perplexity wciąż indeksuje ich witryny, mimo zastosowania blokad. Jak się okazało, mechanizm działania był prosty, ale skuteczny. Gdy standardowy bot Perplexity (PerplexityBot) napotykał blokadę, firma miała przełączać się na „tryb stealth”. Używała wtedy crawlerów z generycznym identyfikatorem przeglądarki (np. Chrome), które dodatkowo działały z puli niezgłoszonych adresów IP i różnych sieci, aby ukryć swoją prawdziwą tożsamość. Co najważniejsze, te potajemne boty w ogóle nie próbowały odczytać pliku robots.txt – pliku, w którym właściciele stron określają zasady dla botów.

Skala problemu była ogromna. Cloudflare zaobserwowało takie zachowanie na dziesiątkach tysięcy domen, a liczba zapytań od ukrytych botów Perplexity sięgała milionów dziennie. To praktyka stojąca w sprzeczności z działaniami innych firm, jak OpenAI, które jasno deklarują swoje boty i respektują dyrektywy zawarte w plikach robots.txt skonfigurowanych przez właścicieli stron.

W odpowiedzi na te odkrycia, Cloudflare podjęło zdecydowane kroki. Po pierwsze, firma usunęła Perplexity ze swojej listy „zweryfikowanych botów”, co utrudni jego interakcje ze stronami chronionymi przez Cloudflare. Po drugie, wprowadzono nowe, heurystyczne zabezpieczenia do swoich reguł. Zamiast blokować konkretne, znane boty, system będzie teraz automatycznie wykrywał i blokował podejrzane zachowania, takie jak próba ukrycia tożsamości przez crawlera. Ochrona ta jest dostępna dla wszystkich klientów Cloudflare. Co ważne, z wdrożonej ochrony przez Cloudflare mogą skorzystać nie tylko podmioty odpłatnie korzystające z usług sieciowego giganta, ale także użytkownicy planów darmowych.
