**Reason:** Considering the **modular** approach XMTP has for content types through the usage of Codecs, and in combination with the allow/block functionality at the address/conversations level, I think It will be completely possible to add the same functionalities but for different content types, at least for standard codecs. ---

Hey, welcome, and thanks so much for the suggestion! If my understanding is correct, you’d like for users to be able to block or allow messages of a certain content type. What are the use cases you envision for this functionality? ---

Hi @saul, yes that´s correct. The primary reason is for privacy settings from the users but also to avoid unnecessary node loading with undesired data. I really think this can be an XIP because the code is modular well split so It will not take long to send a proposal with the changes. What are your thoughts? Thanks in advance!
