A Kolkata blog posted false defamation about my business; how do I remove it?

Online defamation is prosecuted under Sections 351(1) and 356 of the Bharatiya Nyaya Sanhita and Section 67 of the IT Act if the content is obscene. Send a legal notice to the blogger and the hosting platform seeking removal within a fixed period, and follow up with an FIR at the Kolkata police station if the post is not withdrawn. The IT Rules, 2021 require intermediaries to take down defamatory content within 24 hours of a complaint. The Calcutta High Court can grant a John Doe injunction restraining further publication and direct the search engines to de-index the offending URLs. West Bengal Premises Tenancy Act 1997 does not change the substantive law of defamation, which is central, but the local court in Kolkata has territorial jurisdiction where the post is accessible. Preserve the URL, screenshots and the WHOIS data of the domain before the post is edited or removed. Claim damages for the loss of business reputation caused by the post.
