Having a payout schedule every week is a joke. I rather him take the extra minute or two if that and post a proper update.
Only thing I care about is the slimy scammer taking time to post balances and let people get their coins finally. If not going to happen should just close down his pathetic, loser, scammer site already.
However long it takes to get an update, there is no definitive evidence that it's a scam.

Not paying anyone looks a lot like an evidence of scam to me

Are you expecting him to post a message telling you "Sorry It was a scam, I won't pay you" ?
(except for the Bobsurplus/BitBay story, I never saw a message of a scammer acknowledging he/she was scamming everyone)
