And the last step is acceptance. Filtering by hashtag or blocking streams only works if other people are playing by the rules—and, as we all know, enforcing any rules online is a sucker's bet. Accept that you will get hit by stray spoilers in any social media space.
"Being on Twitter while major TV dramas are happening carries with it an inherent risk," Reid says. "If it truly matters that much to you to know absolutely nothing about these shows, you should go radio silent for a few hours."

"I am really conscientious about using hashtags when I tweet about TV, and I wish it were possible to enforce 100 percent compliance with my personal standard across the board," Ariano says.

"For social media—especially with Twitter—it's often about the shared viewing experience," Zap2It editorial director Brill Bundy says. "Keeping it vague defeats the purpose."
