With increased exposure comes a larger attack surface and you will receive more spam. I see you have about 100 follows and half as many followers, 10 or 20x that and you will notice. Deactivating global feed for free relays helps with the spam as paid relays do a good job filtering out the crap but if the free experience is porn and spam, people stay away. There is no free lunch and that is just right. V4V. 

Your infos won't just stay on some of your chosen relays, they spread, and your npub will be regarded as attack worthy. The again, there won't be much more free lunch as running relays cost money and with more adoption comes higher demand for data throughput and storage, the altruism will run out fast. You will either need to pay for a connection, see ads (which will usher in the censorship), or be on your own node. But why would other relays accept your nodes data upload and offer free downstream to you? There will be many Nostr networks, some isolated, by choice or by force, losly connected by some index servers, and that's okay because that what evolution, freedom and resilience mean.

At least it grows naturally and by the means of all market forces, ideologies, desires, virtues and vices Man. The protocol will find a way.
