That's not a reasonable solution. It might be reasonable to tell one specific person that, but to tell every new person that comes to the boards? If you're going to have a spoiler section and a non spoiler section, you have to do something to seperate them. Maybe if this isn't the answer, breaking the spoiler thread off from films into it's own menu section is an option. But expecting everyone to download Adblock and use it is not what I would call reasonable.
