What is mdni?

It seems like "mdni" could refer to a few different things, but it is commonly used as an acronym for "Minors Do Not Interact," typically found online, especially on social media platforms and in fan communities. It is a tag or warning used by content creators to indicate that the material they are sharing is not appropriate for minors. The content might be mature in nature, involving explicit themes such as violence, sexual content, or other adult topics.

If you're referring to something else with the acronym "mdni," please provide additional details, and I'll be happy to help!
