Yes, BTC Guild has definitely turned to a scam too, like ALL pools, as everyone knows. See:
Payouts Paused - 20:00 GMT to 0:00 GMT
Payouts (automatic and manual) will be temporarily paused for four hours today in order to consolidate/condense the hot wallet file. This is something that is required every 6-12 months as a result of wallet fragmentation causing the payout server to fail in responding to payment requests.
There were a handful of payouts which did not get processed in the last 24 hours due to this fragmentation. Those payouts are being removed from user's history, and will be attempted again once the server is back online.
Sorry for any inconvenience this delay has caused.
