Over the past few hours, we've seen an influx of people posting links to places where you can watch "Before the Dawn" for free.
Of course, a lot of people don't have access to the episode on iTunes (everyone outside the States, for example), or don't want to pay for something they wouldn't have to pay for if CN didn't mess up. They think they're helpful by posting links to sites that offer the episode online for free, or links where you can download them. It is very helpful....
It's also very, very illegal.
Per wikia's terms of use:
"You agree not to use the Service to: [...] Post any illegal or unauthorized content or use for any illegal or unauthorized purposes;"
Do not post links to video hosting, file sharing, or torrent sites. We don't care if you use them, and we won't ask you to admit or deny using them, but you cannot post links to it.
Repeat offenders will be blocked.
