What it does

Perplexity says Perplexity-User "supports user actions within Perplexity".

Because the fetch is requested by a user, Perplexity says it generally ignores robots.txt rules.

What blocking it changes

A robots.txt block for Perplexity-User is a statement of intent, not an enforced outcome. The vendor documentation below says these fetches may not follow robots.txt, because a user asked for the page.
