Should I Block crawler4j?

It's difficult to say without a type. Its purposes could either be good or bad for your website, depending on what it is.

Using Robots.txt

You can block crawler4j or limit its access by setting user agent token rules in your website's robots.txt. We recommend setting up agent analytics to check whether it's actually following them.

User Agent Token	Description
`crawler4j`	Should match instances of crawler4j

# robots.txt
# This should block crawler4j

User-agent: crawler4j
Disallow: /

Instead of doing this manually, you can use the API or Wordpress plugin to keep your robots.txt updated with the latest known AI scrapers, crawlers, and assistants automatically.
