I think it mostly just stops because the attacker gave up lol Luckily Im convinced these larger spam campaigns are benign and meant to encourage real spam solutions I dont think we're quite there yet

That the impression I got, that it's a way of flagging a vulnerability

Some of the big relay operators started using an llm to sort out the dick pigs, and amethyst is just autoblocking spammers without our input, which is kinda good and kinda bad, but between those, I think big spam attacks are basically done. Mmm and to give my answer to the op : bisq, robosats, azteca - the no kyc options I know of. Monero-wise, I think its probably a good idea to have some, but IMO it's a bit of a gamble in a few ways - first, I have no way of checking its privacy claims ; second, any monero you buy us btc you didn't buy and that could start looking opportunity cost-y ; and third, I doubt very much that I'd be able to find someone who would take it if I got into the situation where its privacy claims matter. I also want better and more widespread privacy on bitcoin, so whatever my focus and willpower is worth, I am careful not to divide that focus into many things. If that even made sense... Well anyways, there's my 2 sats

Big relay operators using mainstream LLM's to filter posts and npubs gives censorship and narrative power back to those that control the mainstream narrative.
