Mirrors are the curation tool of the Lens Protocol. They are the protocol's equivalent to reposting or re-amplifying content. Mirrors are treated the same as publications with a few additional checks and a few more minor features.

Since mirrors reference other publications, they are subject to the conditions of the original publication's Reference Module. If a publication has a reference module that limits mirrors only to accounts that follow the original poster, and the mirroring account does not hold a Follow NFT, the transaction to mirror will fail.

Since mirrors only repost existing content, they do not have a ContentURI field and therefore cannot be acted on and they don't have an Act module of their own. Mirrors can have their own reference module, which can define what accounts will be able to mirror or comment on the mirror.
