RE: protecting an innocent person:  any lawyers here?

I have trouble believing that you could get into legal trouble for having illegal incidental data from legitimate activities on your computer. If you can, then we're all in trouble, because it is very easy to put illegal data in your web browser's cache (JPEG and other image file formats let you store arbitrary, not-normally-shown metadata, for example). I don't think it would be hard to convince a jury that the block-chain is like your web browser's cache-- full of lots of incidental stuff that is needed for the system to work, but doesn't have anything to do with you.  Now if you happen to have one of the private keys involved in the illegal transactions, THEN you should go directly to jail....

Adding code to "shun" certain spend-able transactions wouldn't be hard, although I think that's a bad idea for the same reason it is a bad idea to respond to trolls on forums-- you'd just encourage the bad guys by drawing attention to their misbehavior.

a sucker is born every minute. i can't believe people are helping this asshole along with his scam!

I'm lost and puzzled... how many ixc approx would you sell for 1 btc? 1? 10? 100? 100000000000?

* Closing accounts with zero balance after two weeks. There are many scenarios where an account might need to have a zero balance for longer than that. If such a rule is needed at all, it should be at least two years, not two weeks.
* Closing accounts after 18 months of inactivity. There are many scenarios where an account might need to be inactive for longer than that. If such a rule is needed at all, it should be at least ten years, not 18 months.

Bitcoin swings 50% like it is nothing.  It could be made worthless by government intervention.  That is not a safe haven lol. 

especially since this jump wasn't accompanied by any good news, promotion, or anything new at all.

......... most people have never used a bank.
