I'm sorry if you feel this way, but moderating a group of 1200 people includes trying to keep things spoiler-free for those who are rabid about it, despite my personal feelings. It isn't a huge thing to request that such things be given a warning, such as "Warning: Possible Spoiler for DMC" and be put behind a cut. This is the way spoilers for multiple-film fandoms have been handled in every community and mailing list I've been on in fandom for a great many years, and I would consider myself remiss if I didn't request such a small consideration for others in the community. It is simply good manners.
