I can confirm that this site is a scam. On other forums the admin is already banned because he is a scammer. They do not pay withdrawals if you win too much. Avoid this site. You will not get paid if you deposit and win. AVOID!
Saying only without any proofs wont make people trust what you say. You need more than just a post to accuse any sites as scam.
So provide valid proofs if you want to accuse and confirm if this site is scamming you. Anyway, your name looks familiar to me and if I remember it correctly that you were supporting someone who try to ask for bug bounty on other site while the bug does not even exist.
