Well, I run a pool as some people know
I've also been involved in bitcoin for a little while (since July-2011)
and I also write some code here and there.
Anyway, yeah I do have some interest in BTC and I'm not really fond of those who do things that at least I think are bad for Bitcoin.
I've inferred same rather interesting information about SPV mining that may be of interest to any pools out there who also think it's bad for Bitcoin.
One of the details (though many probably already know this) are that: SPV pool simply run a miner to other pools that (what I'd call a 'dead pool miner') listen for block changes and uses that info to generate a new unverified empty block header and then distribute that to their pool's miners through their pool work distribution.
There are other methods that will produce the same result later, but that's the greatest speed up they can use for other pool's blocks.
If anyone has more information regarding these miners, feel free to post here.
I consider it quite appropriate to out these miners since they aren't even mining (when they 'dead pool mine' on my pool)
IP addresses:
120.55.119.224
123.57.173.63
106.187.94.193
192.155.84.181
They 'address mined' at my pool and were using the address:
https://www.blocktrail.com/BTC/address/1J1F3U7gHrCjsEsRimDJ3oYBiV24wA8FuVThey made it easy for me to determine this coz all 4 addresses were doing exactly the same thing to the same BTC address
The first 2 are inside the GFW the other 2 are outside
Edit: I updated the address as a link in case anyone didn't realise the significance
