Spam always follows the rules. Strange that I can't filter them because Ocean as I understand it doesn't mine blocks that have ordinals. Also someone made a fork of mempool.space that shows how much of the block is garbage

Ocean doesn’t include them in the blocks that they mine, but other miners do. Once in the blockchain you have to have them or the crypto hashes break because the block has been modified. You can run a pruned node to reduce the amount of data stored.
