A large portion of this kind of traffic comes from identifiable sources, like Perplexity’s data centers, so Cloudflare could whitelist known safe sources. This seems to be what they’re doing now, a user replied to one of my comments saying their Cloudflare control panel now has the option of allowing AI queries from Perplexity.
Another way is to allow users to apply for session keys providing they obey rate limits and whitelist users with valid session keys. Non compliant accounts could be banned, maybe require identity verification to prevent ban avoidance.
