Can hackers get new content before us?

I have no idea if they do any sort of check on your data files when you log in, but its nice and simple to do something like a crc check, so if the content has changed it wont work.

I'm still not sure if I really like knowing whats in the files, its a bit like when you see a trailer for a comedy that gives away the jokes, you can still enjoy the show, but it would have been even more enjoyable if you had you not known it was coming.
