By the way, what's wrong with the mining pool http://blackpools.pw:3333/static/graphs.html?Day?

If you check the address QdXXBSJNcVYnjWm57KVL797typum4JZ5fe you'll see it's getting about half the reward of each block, but it hasn't got more hash power than the other individual miners (in fact, it has less than some). Has the pool been hacked or has its owner set a 50% donation of each block to his own Offering address? It's become in few days the third richest address of the blockchain (see http://off.cryptocoinexplorer.com/) and will soon be at the top.

Hmm. I think this is because I have the look back period set too far back. It's accounting for shares back 144 hours. This is the default for the p2pool-quarkcoin and my current setting for offerings. Here is the relevant portion of the networks.py:

PARENT=networks.nets['offerings'],
SHARE_PERIOD=15, # seconds
NEW_SHARE_PERIOD=15, # seconds
CHAIN_LENGTH=24*60*60//10, # shares
REAL_CHAIN_LENGTH=24*60*60//10, # shares
TARGET_LOOKBEHIND=50, # shares //with that the pools share diff is adjusting faster, important if huge hashing power comes to the pool
SPREAD=30, # blocks
NEW_SPREAD=30, # blocks

I am going to test a shorter look back time and restart and avoid touching the data directory. There doesn't appear to be anything nefarious going on. I am not sure I can look at a history of hash rates but I think QdXXBSJNcVYnjWm57KVL797typum4JZ5fe had a significantly higher hash rate in the recent past. This address/worker is still getting more work even though his or her hashrate has dropped, because of the lookback period. The pool has 6-8 MH/s in the not too distant past but I am not quite sure how to see the history of worker hash rates. This address isn't my own unfortunately.
