Frequently Asked Questions
What Traffic Patterns Should I Expect From Slack Image Proxy?
Slack Image Proxy usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
Does Slack Image Proxy Follow Robots.txt Rules?
No. Slack Image Proxy is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is Slack Image Proxy Used for AI Model Training?
Not ordinarily. Slack Image Proxy is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Slack Image Proxy Affect AI Search or Citations?
Not directly. Slack Image Proxy's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Slack Image Proxy Access Private Content?
No. Slack Image Proxy has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Verify a Request From Slack Image Proxy?
Agent Analytics tracks Slack Image Proxy visits in real time. You can also check your server logs for requests whose user-agent string contains "Slack Image Proxy". Look for a page and its preview assets being requested without follow-up navigation. Because Slack Image Proxy does not publish a verification method, any client can claim its identity and a log match is only a clue.
