I don't have the cash to pay for a paid relay, but I don't know which relays are smaller ones for me to switch over to. The spam is reduced now that I've filled up my block list but it's not perfect. I've seen a few get through still.

You can visit https://nostr.watch to find relays. Though, this website doesn't mention their capacity or popularity.
Thanks for the list. I will definitely bookmark that and take a look later!
