Should I Block Slack Image Proxy?

Probably not. If you block a fetcher, it won't be able to fetch the metadata it needs to display a link preview. Fewer people will click on the link to your website without this.

How Do I Block Slack Image Proxy?

⚠️ Manual Robots.txt Edits Are Not Scalable

New agents are created every day. Instead, serve a continuously updating robots.txt that blocks new agents automatically.

Set Up Automatic Robots.txt

You can block Slack Image Proxy or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
