I've been playing around with this website as well, so far I've gone through two pay cycles without issue.
Please keep us update on whether withdrawals are working. I am also looking for a good way to monitor the activity (new accounts, page visits, etc.), as I will probably consider withdrawing, if these begin to drop significantly.
Cool and OK, will keep you posted. After next week's payout, I'll make a withdrawal. And a post about it :)
