Proof of Work doesn't solve spam because spammers have more PoW than regular users. In Bitcoin it is effective because its 1 against the cumulative PoW of all others. Also, its effective against redoing history, not spam - see ordinals.

There is no cumulative PoW in nostr, so easy win for the spammers.

lopps solution works because spammers dont care about his blog specifically. When Google replaces their (re)captchas with PoW it will fail within a week.
