They blocked me/ my instance?! 

 seems like a bad reply 

 Mastodon users ab/misuse nostr. They can mute whole instances and hear nothing someone says. I had a user I thought who would not answer me and month later he looked what his instance blocked away from him - and he attacked me ;). They are not real nostr user. 

 oh no! 

 Perhaps it`s a special German problem. There is a community that shares instances that are collectively blocked.
