i am facing the exact same situation...i validated upto 500 people ....updated my password and everything but nothing works

Mind you, I did 2889 validations, as hard as you specified. After a while I got thrown back to provisional check and lost all validations too. I don't even think about the reward anymore, I hope to pass KYC. I don't want to offend any pioneers, but I honestly don't understand what this project actually wants anymore?
