Now that blockchain analysis tools are getting better, I wonder if we'll be seeing more and more criminal activity exposed.

For example, someone linked to this wallet/transaction in a reddit thread, which appears to show one of the $100k payoffs: http://www.walletexplorer.com/wallet/08363b86122e340c

Even just six months ago it would have been hard piece that information together, but Wallet Explorer makes it clear as day.
