Rate-limiting by IP (for example, how fast an user can read or write nostr events) is the most widely used technique to reduce spam on servers that don't require user login.

If nostr gets popular, there will be millions of simultaneous active users.

There are ~2000 tor exit IPs.

If clients start defaulting to using tor for all their users, expect to be heavily rate-limited by most relays.
