Why did he withdraw only once if he had 50 accounts and withdraw are auto and instant?

First suspicious thing I found after checking the site for a while. On the main homepage, there is an information of biggest win http://prntscr.com/p17k6j
The username is Kizaru but when I checked the leaderboard, this username is not even on the list. References: page 1 http://prntscr.com/p17kw7 page 2 http://prntscr.com/p17ldb page 3 http://prntscr.com/p17lmt
But let me think positively, maybe there is a glicth on the leaderboard that makes Kizaru is not listed.
