Just seems like this is all at a great cost to both the UK and US, and yet, does very little to tackle the perceived problem. Link sharing sites continue to exist. As his site was taken down after authorities spoke to him, was any money seized? Either way, if the police feel the matter has been dealt with, I'm not sure what the US aim to achieve out of this.
Perhaps we should compile a list of US based link sharing sites and ask they focus on problems at home before extraditing others. Maybe then the laws and procedures involving such sites will be suitably developed to be able to take overseas.
