Spoilers (no spoilers here)

It should go without saying but any links to unreleased content is a permanently bannable offence. Anything that has not official aired should also be considered spoilers. Be considerate about them.

This confuses me a little. We've had leaks before; sometimes episodes appear online well before airing anywhere. Obviously spoilers should be tagged and signposted, but this is the first time I've seen spoilers be a permanently bannable offence. EqD is treating it equally harshly.
Is there something inarguably different about the latest spoilers? Perhaps how it was leaked?
