News site TorrentFreak says the episodes appear to have come from review copies sent to the press, and were downloaded more than 100,000 times in just three hours.

Based on American novelist George R.R. Martin's fantasy series A Song of Ice and Fire, the saga is a feast of blood, sex and betrayal.
