It’s out of spec and creates a dependency on one relay. There must be a way this is decentralized

AI based decentralized spam detection
#[3] ’s approach seems reasonably lightweight and could be added to any relay. classifying using larger models and frequently retraining them would be heavier but surely possible on larger nodes.
also, federated training is a possibility but makes everything a bit more complicated. i guess the most important question is: what features turn out to be predictive. maybe the protocol itself can be leveraged more (network/metadata).
