Frequently Asked Questions
Should I Block MailRUBot?
Usually not. Blocking MailRUBot may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. Almost none of the top websites we track currently have robots.txt rules for MailRUBot.
Does MailRUBot Follow Robots.txt Rules?
No. MailRUBot is not expected to follow robots.txt directives, 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.
Does MailRUBot Access Private Content?
No. MailRUBot 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.
Why Is MailRUBot Visiting My Website?
Someone shared a link to your page. MailRUBot fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
How Can I Tell if MailRUBot Is Visiting My Website?
Agent Analytics tracks MailRUBot visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "MailRUBot". Look for a page and its preview assets being requested without follow-up navigation. Because MailRUBot does not publish a verification method, any client can claim its identity and a log match is only a clue.
