I found the nostr.band relay did a good job of removing the spam. 
The primal relay seems to of done a terrible job. I think the administrator is busy painting and the relay with the little rocket has done a bad job too. That administrator seems to be busy as well. Maybe he's painting too. 

nostr.wine relay didn't get any spam because it's a paid relay. I'm not a member of it so I'm not sure but spammers can't afford to spam on paid relays. 

It's interesting. I hope it happens again. At first I was annoyed but it's helping me learn things.

 

 Thank you I will try that one! I'm gonna check out the paid one too.
