This address is getting an insane amount of block finds and is causing other blocks to be orphaned. When they find blocks, its usually 4-5 blocks in a matter of a few minutes each day. Could they be trying to pull off that attack described a couple months ago? (I forgot the name of it)
Either way, I notice their blocks are causing other pools to get orphaned. Todays blocks caused a ghash.io block to get orphaned.

This guy is bringing in some serious cash.

For real, wtf is going on there, seems like way to many blocks one after another.

This reddit seems to point to any asian based miner and/or asian based pool operator.

The address did not come up in this blog article http://organofcorti.blogspot.com/2014/01/163-unknown-network-hashrate.html but its interesting to see these unknown big guns pop up on the grid more and more often.

He must have some serious computing power

That's a really big shit..... and there is no information about it yet. There are so many payouts too, it means it is a pool, right?

[rammy2k2]

[Burninj]

What were the heights exactly?

I followed some 'newly generated coins' transactions and found out all those blocks to be from 'discus fish' pool.
Take a look at 'block origin' site

Yes, this is the main Discus Fish address. Just check the coinbase for "Discus Fish" in Chinese. Related pool/hasher: "For Pierce and Paul", address 13NA7X1u18CgGa7RzTDyvuuoLJtLRvXgke. I'm not quite sure how they are related, but they are - they shared a coinbase sig and this generation address for a while.

Yes, I'd already identified it, so it wasn't unknown. Percentage of unknown blocks is now down to 3%.
