VK Message Blocker is a free Chrome extension developed by ivn-ln. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

This extension allows users to block unwanted messages from selected chat members on VK, the popular social networking site. Unlike the standard block function on VK, this extension provides silent blocking, meaning that the blocked users will not know that they have been blocked. Additionally, the extension also blocks messages in chats.

To block someone using this extension, simply click the "Block" button next to the desired user in the VK chat settings. Blocked users can be managed either in the extension's popup or in the VK chat settings.

VK Message Blocker supports both English and Russian languages, making it accessible to a wider range of users.
