No it's perfect for personal use, but I have some other problems. We should discuss about them together guys #[4] #[5]

NIP 65 => If you save only your proxy with this NIP, all other people will try to fetch events from your proxy. If it's a localhost or local network url, they will not reach your proxy. But if it's not, they could add your proxy in their relays list.

This brings up a new problem: Authentication on the proxy. NIP-42 is probably the best solution to only allow your pubkey for using the proxy, but 0 client currently support it.
