It's much more likely that someone making money out of spam bots pays the fee to get onto a paid relay, than that I do.

Yes it’s interesting how the game theory will play out. Will we gravitate to clients that filter out the spam the best, or use free, but by-invitation-only relays, or just not care about it that much and keep nostr wild (at perhaps the expense of greater adoption).
As long as I can block people, I'm good with wild.
