I don't quite understand how you think they would have taken the data from RSC..? Lots of people had LFS license names which were different to their RSC username, and also the vast majority of RSC users would not have been LFS license holders. Do you think they checked every LFS license name for a corresponding RSC account and copied the date? From a programming perspective I can't believe they would have done that. Obviously they wouldn't have manually copied 68,000 accounts either...
