Bypass Robots.txt
Florene Pothoven
While scanning my website with uniscan it found my robots.txt file which disallows access to /cgi-bin/ and other directories, but they are not accessible in browser. Is there a way to access the directories or files which are Disallowed?
The robots.txt does not disallow you to access directories. It tells Google and Bing not to index certain folders. If you put secret folders in there, Google and Bing will ignore them, but other malicious scanners will probably do the opposite. In effect you're giving away what you want to keep secret. To disallow folders you should set this in Apache vhost or .htaccess. You can set a login on the folder if you want.
The robots.txt file isn't a security measure and has no incidence on access permission.This file only tells 'good' robots to skip a part of your website to avoid indexation. Bad robots don't even abide by those rules and scan all they can find. So security can never rely on the robots.txt file (that's not its purpose).
If you don't want your crawler to respect robots.txt then just write it so it doesn't. You might be using a library that respects robots.txt automatically, if so then you will have to disable that (which will usually be an option you pass to the library when you call it).
I know that here www.w3.org/TR/html4/appendix/notes.html#h-B.4.1.1 it says spiders always check the robots.txt before going to page. However I have recently been told that Google crawls every single URL that it can find on a site and then looks at the robots.txt file and filters out what is disallowed. Is this true?
To entirely prevent a page's contents from being listed in the Google web index even if other sites link to it, use a noindex meta tag or x-robots-tag. As long as Googlebot fetches the page, it will see the noindex meta tag and prevent that page from showing up in the web index. The x-robots-tag HTTP header is particularly useful if you wish to limit indexing of non-HTML files like graphics or other kinds of documents.
So if you really don't want your pages indexed then make sure to use a META tag or HTTP header. I've found particularly helpful for back-end admin areas and control panels when I don't trust Disallow: /admin to be good enough.
Google may index the URL but not the contents of a page if it is restricted by robots.txt or a robots meta directive. This is, providing that nowhere else on the web links to the same destination without a nofollow link relationship.
robots.txt are the instruction not the compulsion. Google normally index the page that you have blocked in robots.txt specially if you have links pointed to blocked page. Even if that page has noindex tag and links have nofollow tags.
MattCutt have told this in his official video and he gave the example of Ebay and white house gov websites. Few years back they had blocked the search engines but due to large amount of requests Google have to crawl and index the websites. now it is a normal practise by google. I think below is the video i am talking about. -txt-remove-url/
The Robot Exclusion Standard is purely advisory, it's completely up to you if you follow it or not, and if you aren't doing something nasty chances are that nothing will happen if you choose to ignore it.
That said, when I catch crawlers not respecting robot.txt in the various websites I support, I go out of my way to block them, regardless of whether they are troublesome or not. Even legit crawlers may bring a site to a halt with too many requests to resources that aren't designed to handle crawling, I'd strongly advise you to reconsider and adjust your crawler to fully respect robots.txt.
There are no legal repercussions that I'm aware of. If a web master notices you crawling pages that they told you not to crawl, they might contact you and tell you to stop, or even block your IP address from visiting, but that's a rare occurrence. It's possible that one day new laws will be created that add legal sanctions, but I don't think this will become a very big factor. So far, the internet culture used to prefer the technical way of solving things with "rough consensus and running code" rather than asking lawmakers to step in. It would also questionable whether any law could work very well given the international nature of IP connections.
(In fact, my own country is in the process of creating new legislation specifically targeted at Google for re-publishing snippets of online news! The newspapers could easily bar google from spidering them via robots.txt, but that's not what they want - they want to be crawled, because that brings page hits and ad money, they just want Goggle to pay them royalties on top! So you see, sometimes even serious, money-grubbing businesses are more upset for not crawling them than for crawling them.)
Website owners tell web spiders such as Googlebot what can and can't be crawled on their websites using robots.txt file. The file resides on the root directory of a website and contains rules such as the following;
When a website is in staging or development, it should be restricted from being crawled and indexed by the search engines. This avoids it ranking in the search results, and potentially competing and cannibalising with a live website.
Various methods are used to block search engines from a staging site, or to avoid content from being indexed, including putting it behind a login, using robots.txt, noindex and more. Staging servers typically lack the performance of production, and websites still in development are generally more fragile as well.
Staging websites are usually restricted from being crawled by search engines and crawlers. There are various methods to prevent crawling, and each require a slightly different approach or configuration to bypass.
The most common is basic and digest authentication sever authentication, which you can see in a browser when you visit the website and it gives you a pop-up requesting a username and password.
This feature is powerful because it provides a way to set cookies in the SEO Spider, so it can also be used for scenarios such as bypassing geo IP redirection, or if a site is using bot protection with reCAPTCHA or the like.
We have seen some test areas of a website only display an updated page when a specific cookie is supplied. This is often not on staging servers, but full production websites when changes are tested in limited form.
The default 5 threads used by the SEO Spider should not generally cause instability. However, we recommend speaking to developers pre to crawling, confirming an acceptable crawl rate if required, and then monitoring crawl responses and speed in the early stages of the crawl.
The staging and existing live site URLs are then mapped to one another, so the equivalent URLs are compared against each other for overview tab data, issues, and opportunities, the site structure tab, and change detection.
So OpenAI and Anthropic are apparently choosing to bypass robots.txt and scrape all parts of a given page, according to TollBit, a startup that facilitates paid licensing between publishers and AI firms.
Both OpenAI and Anthropic publicly claim to respect robots.txt. But generative AI companies, including OpenAI, have argued to regulators that any publicly accessible content on the internet is open to fair use for training AI models.
Streaming services should also be more cautious with bundling plans, these TV insiders advise, since adding too many discounted sign-ups can painfully lower the total lifetime value of those subscribers.

If Chrome imitates Apple, there may be a de facto deprecation of the third-party cookies, since potentially only a slim percentage of users would consent to tracking. In that case, advertisers would still have to primarily rely on cookie alternatives, including the Privacy Sandbox.

This will be recognized by my firewall, where I have set up rules to block any source of connections, that would try to open one of the fake urlpaths from the robots.txt file. Once on the block list, the bot will not be able to spider any of my pages, no matter if allowed or not.
E.g. if your website is you could create a folder /personal under the root of the website and not reference it anywhere on the main site. Instead, you could send someone the direct link via email. People do that often for large files, they want to share with someone.
My firewall is a WatchGuard, that has a http proxy, where you can set up different urlpaths, that you want to allow, deny or block (block means, that you put the source of the connection on a temporary blocked sites list).
Certainly, an interesting use of the robots.txt file. Question: So, based on the crawl pattern I believe you block the IP address of the bots (assuming that they are the bad ones)? What if that was a genuine IP address and some hacker/scraper was just using it to launch the bot program?
