The information from this post says you're posting to relay.nostr.band and relay.damus.io .

The issue is that these relays don't have any moderation on the text content being posted. This isn't a judgment on their moderation choices, but to point out that users have choice in where their data goes and should choose relays that they align with. That's the easiest solution. You won't be subjected to this content and anyone else who wants to get your content would need to connect there as well.
