Users have a hard time seeing my posts using Amethyst. Some say they needed to remove the Security Filters option. other users say that turning Security Filters back on automatically blocked me on Amethyst.
Vitor said I need to delete whatever posts were made that set off the spam filter. I have no idea what Vitor considered Spam that happened months ago.
So yes, that is censorship at the app level. Vitor is literally curating peoples Nostr experience.
