I believe them.Dear Players,
It is with deep regret that we have to temporarily suspend current operations.
This suspension is due wholly to the fact the Zetpoker.com has not received any player settlement payments from the network/operator for some time.
We are currently pursuing all avenues to secure the timely receipt of players payments and will keep all players informed of developments over the coming week.
ZetPoker Management
Revolution Gaming, whether it's currently owned by Lock or not, is in big trouble.
I am assuming that Zetpoker is probably owed money by Lock Poker (the biggest skin), and since Lock hasn't paid the network, Zetpoker also can't get paid.
