Yeap this was really smart idea to write on twitter. Don't go there SteamGAF if you haven't watched movie because there could be some jerk with spoiler tweets. I will only post image without link to the tweet.
Facebook is not any better when it comes to spoilers really. At this time when you want to keep something special either ignore social media and some forums or dont wait too long cause the chances of getting spoiled are easy.
Thankfully I haven't experience any big spoilers yet but Ive seen meltdowns before over Uncharted spoilers and film spoilers.
