Presently (March 2024) anti-bots are actively applied for web data protection. Some of them with their characteristics & bypass methods might be seen here. If you are interested, take a look at some bot protected websites table. In this post we’ll share our real case experience with fighting CloudFlare proection.
Tag: anti-scrape
Amazon scrape tip
Recently we’ve met requirements to scrape Amazon data in big quantities. So, first of all I’ve tested the data aggregator for being bot-proof or anti-bot protection. For that I used the Discord server Scraping Enthusiasts, namely Anti-bot channel.
Since Amazon is a hige data aggregator we recommend readers to get acquainted with the post Tips & Tricks for Scraping Business Directories.
Over 7.59 million of websites use Cloudflare protection, 26% of
them are among the top 100K website worldwide. As Cloudflare
establishes itself as the norm regarding service protection, chances are, the site you want to scrape is more likely to use it than not.
When it comes to scrapping websites, captchas and other type of
protections were always the main obstacle in providing reliable data collection solutions. And most often this would lead to consider bypass services which aren’t always free.
Selenium comes with a default WebDriver that often fails to bypass scraping anti-bots. Yet you can complement it with Undetected ChromeDriver, a third-party WebDriver tool that will do a better job.
In this tutorial, you’ll learn how to use Undetected ChromeDriver with Selenium in Python and solve the most common errors.
How to bypass PerimeterX
You’ve found the website you need to scrape, set up your scraper and fired it, just to sadly realize PerimeterX has blocked you.
PerimeterX’s dynamically complex bot detection system relies on server-side and client-side checks to distinguish humans from bots. It deploys several layers of protection and, for the most part, manages to do its job without interrupting the user experience.
But don’t fall into despair! There are a couple of things you can try to bypass PerimeterX (called HUMAN now) before giving up on your goal of scraping that delicious data.
Today, I’ll share of a Dicord server 1 and server 2 that accomodate a bot able to detect multiple modern scrape-protection and scrape-detection means. The server’s channels with the bot are #antibot-test
and #antibot-scan
respectively

Recently we encountered a website that worked as usual, yet when composing and running scraping script/agent it has put up blocking measures.
In this post we’ll take a look at how the scraping process went and the measures we performed to overcome that.
In the post we summarize how to detect the headless Chrome browser and how to bypass the detection. The headless browser testing should be a very important part of todays web 2.0. If we look at some of the site’s JS, we find them to checking on many fields of a browser. They are similar to those collected by fingerprintjs2.
So in this post we consider most of them and show both how to detect the headless browser by those attributes and how to bypass that detection by spoofing them.
See the test results of disguising the browser automation for both Selenium and Puppeteer extra.
Given: a webpage to scrape.
If you inspect the DOM tree of that page you will find that quite a few tags are having the keyword dist. As an example:
<link rel="shortcut icon" type="image/x-icon" href="/wcsstore/ColesResponsiveStorefrontAssetStore/dist/30e70cfc76bf73d384beffa80ba6cbee/img/favicon.ico">
<link rel="stylesheet" href="/wcsstore/ColesResponsiveStorefrontAssetStore/dist/30e70cfc76bf73d384beffa80ba6cbee/css/google/fonts-Source-Sans-Pro.css" type="text/css" media="screen">
