What a bot for ads, link previews or SEO tools does

These bots work for a specific product: checking an ad's landing page, drawing the preview when a link is shared, or collecting data for an SEO tool. Some only visit because the site owner asked them to.

Slack says it does not read robots.txt, since it acts for a person and does not follow links.

Block or allow Slack-ImgProxy in robots.txt

Add one of these to the robots.txt file at the root of your domain. Crawlers read it before they fetch anything else.

Block Slack-ImgProxy

User-agent: Slack-ImgProxy
Disallow: /
