Great article! One note:

> If the attacker chooses not to use Schnorr signatures and continues to use old signatures, then other users that do use Schnorr will still have smaller transactions to send and will thus have to pay less. This would still make an attack more expensive than before.

> While the price for these spam attacks is estimated to be in the millions of dollars, this is a tiny investment for any wealthy individual(s), government(s) or large corporation(s), that wants to sabotage the network.

This only applies to the case when the spammer is not the miner who actually mines the block…
