I meant the other way... how much is the pirate closure tainting say the receiving addresses of the last 10 transactions (or 10 random transactions since we are getting close to his weekly payout time)?
Feel free to use the block parser to gather you own stats and reach your own conclusions

$ ./parser taint file:PIRATE-SPENDS
fatal: file:PIRATE-SPENDS is not a valid TX hash
Aborted (core dumped)
It seems like github doesn't have your newest version. I don't think it has the ability to load keys from a file for the 'taint' command in the version you published...
