It's fandom secrets, get used to it. Now, if this was a [whatever the hell show that icon is from] community, then your bitching might carry some weight because most of those types of comms have spoiler policies. If you are really avoiding spoilers that desperately, then hole yourself away from the internet for a while (or at least from a place like fandom secrets where you are taking a chance of being spoiled for just about everything) like I do whenever a new Harry Potter book comes out.

Lastly, calm the hell down. Your reaction is way disproportionate to the offense. This too shall pass.
