What it is

The other half of Slack's pair: the agent that reads robots.txt and handles Slack's non-unfurl fetches. Slack documents both strings on one page.

What blocking it costs you

Slack stops being able to read your robots.txt, which is a strange thing to want. Block the link expander instead if that is the goal.
