Reddit is now blocking the Internet Archive (IA) from indexing popular Reddit threads after allegedly catching sneaky AI firms—restricted from scraping Reddit—instead simply scraping data from IA's archived content.

Reddit has moved to restrict the Internet Archive’s Wayback Machine from indexing most of its platform after identifying that some artificial intelligence companies have been using archived Reddit content for data scraping in ways that violate its policies.

The Internet Archive can now only crawl Reddit's homepage. Reddit's goal is to block AI firms from scraping Reddit user data. Publishers (and others) are suing AI companies for copyright infringement.
