I'm going to begin moving my relays around, choosing WoT, paid, and public relays that mitigate spam, but most of all, moving away from Blastr. We'll see how it goes over the next month. 

 How can you see if a (public)relay mitigates spam? 

 Experience. I know that relay.damus.io, relay.nostr.band, and nos.lol mitigate spam. nos.lol has problems recently but seems to have fixed the issue. 

 Aah oké, not that you can look up per relay what it does.
Thanks for sharing. It still is hard to comprehend with al the relays and how to use them and choose which are for what.
