Block just hides the person from your view. It doesn't affect the person at all. Reporting does. Block is just for you. Reporting is when you are warning everyone else

do blocks get saved to the mute lists?
Yep, but on the private side of those lists. Only the author can see it
Ah, now I understand. I thought it was one and the same on Amethyst. I have now looked at the function on Amethyst again and now I get it. Thanks for your feedback!
looks like “block” in amethyst is exactly what you looking for
Can you please answer one more question for me? What does "Spa" actually mean for the relays at the top right?
it says spam but I’m not sure exactly what that quantifies 
Thanks for your answer! So spam means that. On my smartphone it just says "spa" so I didn't get it. OK spam then. But what does it mean now? Like my posts have been reported as spam by someone? Or does that mean spam from others?
Yeah, that screen is up for a massive restructuring :)
Spam :)
