Personally I believe pooya87 is right, but not in the way that he believes. Ordinals itself is not the attack, but an attack vector that could be used to launch an actual "attack", but which their maximum "damage" is merely maximum annoyance caused by high fees.
But that's also the fee market serving as a defense mechanism for such an "attack".
I suppose that's fair.
Why doesn't he use the Gold blockchain for that and inscribe each drawing on a bar of Gold. Haha.
I'm actually quite surprised he didn't make SchiffCoin, that way he could have complete control over the project from the ground up. Maybe its because its sounds a bit too much like "Shitcoin".
