This OP_RETURN stuff has really split a lot of bitcoiners I wouldn’t have expected to see on different sides. My 2 sats: if it’s paying a high enough fee to be mined it is not spam, end of story. Trying to argue what is and isn’t a worthy transaction is a dark road to try and go down. Check’s inscription of his dead dog on the blockchain (which he will have paid for) is just as valid as my random test transactions I’ve made when setting up a wallet. Before you know it they’ll say a ‘monetary use’ has to be above a certain value or something. Spam is data being relayed that isn’t able to be mined. Stop trying to argue the morality of other peoples transactions.
