Robots.txt cannot be completely trusted. There are many unknown crawlers that completely ignore robots.txt, so they must be blocked from the nginx server to make the website more secure.you can use block the specific crawlers in your robots.txt, hope that helps brother![]()
Lots of crawlers, most popular ones are from google, bing, yahoo, and social media sites. The question is why you consider them garbage.Brother, what kind of garbage robots are there? Ua or features
Go to your nginx server block configuration and add a 'deny' directive. Target shady user agent strings, i will list some resources for that below, and restart and clear cache.Robots.txt cannot be completely trusted.

Thank you for your reply. However, this is not ideal. Because the IP of the robot will change after a period of time. Do you know the iconic features of those garbage robots? For example, ua:GoogleLots of crawlers, most popular ones are from google, bing, yahoo, and social media sites. The question is why you consider them garbage.
Go to your nginx server block configuration and add a 'deny' directive. Target shady user agent strings, i will list some resources for that below, and restart and clear cache.
I will apply a list of known malicious IP's so you can block them in your server.
Hope this helps

Identification, Content Specificity, Robots.txt compliance, Device and Platform Information, Compression Support, and VersioningThank you for your reply. However, this is not ideal. Because the IP of the robot will change after a period of time. Do you know the iconic features of those garbage robots? For example, ua:Google
I've never found any issues with generic crawlers on my servers, they consume minimal resources. If you feel your server is clogged, maybe its a matter of configuration, just increase your workers, add more hardware resourcesThank you for your reply. However, this is not ideal.

Yes, as long as you know his unique characteristics, you can use nginx to block him.Identification, Content Specificity, Robots.txt compliance, Device and Platform Information, Compression Support, and Versioning

If you are obssessed with those crawlers, why don't you get their footprint by yourself? Just get your nginx logs, and filter out the most common user agents for your regular visitors.
Anyway here is a site that offers most common UA for both browsers and crawlers, but still I would only focus on browsers and filter out. You will end finding out that its not as terrible as you believe.
