I'm talking about perplexity's behavior. Perhaps there's a point of contention on perplexity downloading a document on a person's behalf. I view this as if there is a service running that does it for multiple people, then it's a bot.
But “for multiple people” isn’t an argument IMO, since each of those people could run a separate service doing the same. Using the same service, on the contrary, provides an opportunity to reduce the request volume by caching.
