Do Not Reply cards and other mechanisms used to explicitly outline what interactions are unwelcome to a post are called “boundaries”. Boundaries are good. They are good for bother the setter and the receiver. It is loving to tell someone what is not welcome, and loving to have them respected. If you are upset that someone is stating a boundary, it is likely that you are not familiar with boundaries and I’d like to tell you that you too deserve to both set them and have them respected.
