Does Perplexity bypass robots.txt restrictions using hidden bots and variable user agents?

The article on the Cloudflare blog focuses on the issue of stealth crawlers that operate without adhering to website crawl directives. It provides a detailed account of how Perplexity employs these 'stealth undeclared crawlers' to bypass the rules that site owners can impose. This not only violates ethical standards but can also affect the performance of websites, which may struggle with server load due to unauthorized indexing. The author emphasizes the importance of following norms and clear communication between website owners and the robots that visit them. As the number of hidden scraping techniques increases, website owners need to be more vigilant to protect their resources and user data.
