Allow or block Discordbot

Block Discordbot

Asks Discordbot not to crawl any page. Well-behaved crawlers stop; it does not stop anyone who ignores robots.txt.

Should you block it?

Blocking Discordbot breaks the preview card when someone shares your link on Discord.

How to verify a Discordbot request

  1. Find the IP address of the request in your server or CDN logs.
  2. Get Discord's published list (Discord IP list).
  3. Check whether the IP falls inside one of the ranges. If it doesn't, the request is not from Discordbot, whatever its user agent says.

Questions about Discordbot

Is Discordbot safe to allow?

Discordbot reads public pages; it does not log in or submit forms. Whether to allow it depends on whether you want Discord's product to use your pages.

How do I know a request is really Discordbot?

Check the request against what Discord publishes: Check the IP against Discord's published list. The user agent alone proves nothing.

How often does Discordbot visit?

It depends on your site; Discord doesn't publish a schedule. Referscope shows the real visits.
