As far as Im aware the pools are being tested and the payout portion isn't complete. This means the pool is likely finding blocks but not paying out yet, this is why www.moneropool.com is offering a payout later depending on how much hashing power you contribute. There's no way of knowing how many blocks they find so for all you know they could be finding loads and end up making money off peoples hashing power.
Thats why they're in test, mine on one if you want but know you might not be getting your fair share.
I dont understand this point. If they definitely aren't finding blocks then you wouldn't get paid either way.
