If a new server (not like ruby, electus etc.) does not post their contract with their server provider to prove that the server will be hosted until some time, do not donate, do not trust or invest your time or you'll lose both your money and time.
One thing for sure, if it doesn't take a couple of months of development for the "new features" there'll be a shit ton of bugs like there was in this server. If the server owner plans to scam players and run away with the money, it would be dumb to invest 2-3 months time to develop new features or resolve existing bugs. Long story short, if there are a ton of bugs and no proof of long time development or investment, don't bother to start. It's obviously a scheme.
