We keep deleted texts locked away in our archive (unless you insist on them being deleted for good). Texts in our archive are not accessible to the public, and are usually never seen again by anyone.
Why do we do this? For copyright reasons. Imagine the following situation:
Let's say you puplish a poem on Belletristica in spring. Then, in summer, someone steals it and publishes it on another platform. You delete your poem in autumn. Then, winter comes, and you discover the stolen text on the other platform. Now we can check the archive and say: "Hold on, this text has already been uploaded on Belletristica this march!" and do what we can to help you enforce your copyright.
You can of course demand the complete deletion of your texts from the archive, and we will take care of it quickly. However, if you choose do that, we can't help you with any copyright disputes over this text in the future.
