Get yourself a good pay relay my friend and get out of the Amethyst default message groups to avoid this.

Can you make any recommendations?
I recently setup my own paid relay at https://relay.bigred.social if you'd like to join!
Yes, nostr.wine is a fine Relay. But you can search old threads from #[5] that are amazing about introduction to Nostr and pay relays.
https://relay.exchange/ the first 10-12 are good. I use some of that list.
