I think there is something fishy going on. They mention hosting a blossom server so it may be that they have received and ignored abuse reports relating to copyrighted material or CSAM. It also feels unusual they would say “nostr is not allowed”, considering most people or hosts do not know what Nostr is. I want more details about the exchange. If they were asked to take down the content. As is, screenshots (ofc redacted personal info)
