Mempool node policy is extremely important for private node runners as good mempool hygiene (filters) reduces the transactional burden on the node, and by extension the #bitcoin network. Nodes are to remain simple with very low overhead in order to assure that there are more numerous voluntary node operators world wide. Keeping the network decentralized. Filters do work at the node level, your little bullshit transaction ended up in the time chain, sure. But nodes with good policy didn’t have to relay it to each other, thus increasing the burden to operate them. Additionally, the more spam like this that ends up needing storage on the time chain, the more memory will be required over time, increasing the burden on nodes even more. When individuals stop running nodes because of this and it’s left to the big cloud and server farms, #bitcoin losses. Why tf can’t people see this shit, it’s baffling.
