You're being marketed ring size of 16, but in reality you're getting 4-5. This is why you guys are changing it again, bc you got it wrong last time. As for the spam, it's a real issue & that is why they want to change the fee structure again, bc you got it wrong last time. You have no idea how many daily txs are spam aiming at that ring size of 4. You only have ~25k daily transactions, that's an easy target unless the fee structure is addressed.
