Great work, and so great of you to open-source this - I really hope you keep it that way!
Would be really cool to set this up and set the server up to do some proxy-hopping to make IP tracking more difficult as well, regardless of client device and when roaming.. While I'd be more leaning towards self-hosting, if you set this up as a subscription service, your users will also benefit from sharing the same pool of IPs (though I imagine you'd also face issues with getting flagged/blacklisted/CAPTCHAd a lot through abusers and bots, that will be significant work to polise if you go that route).
