Anyone who was mining on the pool with an apollo, it's blocked from mining PPLNS - only allowed mining Solo.
As mentioned in their thread, they've not bothered to do proper block level testing, so they're relegated to Solo for now.

User „wavelengthsf“ said he found a block on the testnet. Isn‘t this enought to confirm that the Apollo can find a block?
No.
Being able to find a share is not enough proof that a miner works.
A testnet block is actually pretty much the same as a bitcoin pool share.
A miner needs to be able to handle 64 bit shares before it is at least considered tested.
Their code is hidden, so you can't check it either.
A block is just a share with much higher difficulty, the miner doesn't need to know when a share is a block.
Genesis, running buggy software that didn't handle 64 bit shares, was the reason slush lost 28 blocks in a month back in Dec 2015
Alas the apollo team has already claimed that being able to mine any share is good enough testing of their miner.
It's certainly a concern that they sell a miner that isn't even properly tested but leave testing up to the people who buy the miner.
However, I do already know that it works for greater than 32 bit shares.
Someone else has run the miner long enough solo mining on my pool to prove that.
I wonder what their response would have been if I had found proof that the miner didn't handle 64 bit shares ...
Alas apollo has stated that they will create a 32 bit version of their miner, and who knows if that will work, or how to identify the 32bit version.
So until I can see that the 32 bit versions also works, it will continue to be restricted to solo.
