Hi,
We've checked http://blockchain.info/pools again and still couldn't find 50BTC.com on diagramm.
It seems very strange, cause we have more than 1,1 Th/S. An we've found lot of blocks.
It is some special attitude to us?)))
Could we somehow handle it?
Did you give them a list of your IPs? Because if they show up in the list of unknown IPs under the pool graph then that means they haven't linked the IPs to your pool yet.
I did a quick look. Maybe you are 176.9.135.190? That seems near your 50btc.com @ 176.9.130.31 or pool.50btc.com @ 176.9.130.35. I'm answering because I happen to mine at 50btc.
You could look up your last block on blockchain.info and see what it says for "Relayed by" IP.
I see 5.9.24.81 for your 3 most recent blocks which means you'd be the #1 unknown IP with 11 blocks not being tagged as 50btc.com
