It was bound to happen. Due to legal pressures, TorrentSpy has gone ahead and blocked US visitors from their search, noting the reason as being privacy concerns. If you recall, the MPAA sued TS last year, which resulted in a judge ordering the site to begin tracking users so that the information could be used in the future. They continued to allow US visitors use the search for many months following, but apparently the hassle has become too great.
While TorrentSpy is appealing the court ruling, it has decided to block US users rather than give up their personal data to the MPAA, keeping in line with its initial privacy policy. The site is still accessible, and you can browse to your heart’s desire, but performing a search on TorrentSpy will give you a message from the company explaining its decision to block US users and a list of other sites to visit.
