agree with hazek, try to avoid calling it taint analysis.
Maybe coin history/origin analysis or something else.

So something weird is going on with my vanity address.
http://blockchain.info/taint/11235813yoNV9F45KjwRiBYnYFufMunTj8Apparently there is only a 5.7942159848% that this address is connected to itself. That seems wrong.
Also I think you have a typo here: "The more "taint" the worse the stronger the link that remains."
