Wow, I didn't realize about 25-50% of each new block height are ordinals inscriptions, no wonder why the network has been busiest than ever lately.
This is another difference between this attack and its predecessors. This time in the Ordinals Attack the spam transactions carry a clear sign of being a spam transaction whereas in previous spam attacks such as the last big one in 2017, it was very difficult to distinguish between a spam transaction and a regular transaction in a lot of cases (not all though).
usually normal people dont re-spend their money every 10minutes.. constantly each block for days
when funds are being spent with only low confirms its obvious these payments are not normal people buying goods or services.. thus spam
ordinals is just bloated spam (double attack)
