Blossom-based Media Servers: please clearly identify on your website if you accept encrypted files or not ("application/octet-stream"). Our users are looking for options.

Our DM uploads now always encrypt to the receiver. File hosts will not have access to the keys to see what the file is about. But you do have the uploading user's auth.

We probably need to define a way for DM users to report CSAM content to you. But we do not have a NIP/BUD for that today.
