But that's the "problem" with Ordinals, some of those being built, and communities formed, might be incentived to keep "spamming" the blockchain because some users found out that dick pics/fart sounds are valuable, and they could make profit from them. It's not a real problem by itself, but it's definitely an inconvenience for users who want to use Bitcoin for financial transactions.
