I found primal and the relay with the little rocket were the worst. If you look at the contact information and click on the administrators of the relay it seems they are not very active. 
They must of both gone painting and ended their careers as sysadmins. 
Primal doesn't delete drafts because I added them and my drafts keep coming back. 
It's not a good relay  

 Agree about Primal. So many ReplyGuys come through that relay. I recently deleted relay.primal.net and that BS ReplyGuy spam immediately dropped.
