From the Spoiler policy: "spoilers are permitted after the episode or comics issue in question is released officially in at least one English-speaking country. "

While it doesn't explicitly mention online content, it has been released officially in at least one English-speaking country. Thus, it maybe spoil some things, but it's not a spoiler for the wiki.
