This has been long the case! I think there whole business model is based off scraping lol

This could be OpenAI, or it could be another company using their header pattern.

It has long been common for scrapers to adopt the header patterns of search engine crawlers to hide in logs and bypass simple filters. The logical next step is for smaller AI players to present themselves as the largest players in the space.

Some search engines provide a list of their scraper IP ranges specifically so you can verify if scraper activity is really them or an imitator.

EDIT: Thanks to the comment below for looking this up and confirming this IP matches OpenAI’s range.

Thousands of systems, from Google to script kiddies to OpenAI to nigerian call scammers to cybersecurity firms, actively watch the certificate transparency logs for exactly this reason. Yawn.
