What is blokkr?

As an AI language model, I don't have access to current and updated information regarding blokkr. However, Blokkr is likely a misspelling of Blocker, which refers to a technology that prevents ads, pop-ups, and other kinds of content that are deemed unwanted. Blockers are widely used as plug-ins on web browsers or as standalone applications, with the primary purpose of enhancing internet browsing experience. They are also used to reduce the risk of malware attacks and in some cases, protect user privacy.
