We are not trying to earn any revenue from it. We pay hosting out of our own pocket and we are currently in a financial state that allows us to do so. And the site will be 100% free, without any house edge even after the beta.
From what I've seen on faucet abuse in the past, I highly doubt this is a sustainable "business" model.However, you wouldn't be the first website to start free and add advertising or payments later once the site becomes very popular. If that's part of the business plan, it kinda makes sense
And to be frank, for me and probably for other users too this approach of "we're giving out a service for free" makes me think twice about their trustworthiness.
Someone who acts like that has to either be a millionaire philanthropist or a scammer... we all know which of the two is more common in the internet!
Personally I've made free software without adds, but those have helped communities without me losing money, they've helped me grow my skills and also pocked some little money from donations.
