Andrew Lincoln and Norman Reedus Andrew Lincoln and Norman Reedus

Someone needs to march on down to AMC and teach the network a little thing about time zones and social media because whoever is handling the online promotion for The Walking Dead totally blew it last night.

[WARNING! Spoilers for Sunday's episode of The Walking Dead follow. See, that wasn't so hard, was it AMC?]

Fans of the zombie drama were rightfully outraged when the Facebook and Twitter accounts of The Walking Deadfilled their feeds with a big honking spoiler of the very same event that actors had been teasing all week long before it aired in a big chunk of the United States. Following the East Coast airing of "Coda," The Walking Dead's midseason finale, AMC Facebooked and Tweeted the following picture:

And just to make it clear that Daryl Dixon (Norman Reedus) isn't carrying a napping Beth Greene (Emily Kinney), the #RIPBeth hashtag definitely indicated that she was a goner. Facebook and Twitter don't discriminate between time zones and don't care if viewers are too busy to watch episodes live, so those on the West Coast and others who planned to watch it on-demand or on their DVRs learned of the episode's devastating event before they had a chance to see it.

In the final moments of the episode, Beth made a last-minute decision to stab villain Dawn with a pair of scissors after a hostage exchange between Dawn's group and Rick's group. Dawn responded by blowing Beth's brains out with her pistol. Read our recap here.

Twitter replies and Facebook comments were littered with expletives from those who were spoiled, and can anyone blame them? Networks may be clueless about a lot of things, but this is elementary-level Internetting we're talking about here.

Late Monday night, AMC took to Facebook to apologize for the error.

"We heard your feedback to last night's post, and we're sorry," the statement read. "With zero negative intent, we jumped the gun and put up a spoiler. Please know we're going to ensure that, in the future, possible spoilers by official AMC social feeds are killed before they can infect, certainly before the West Coast (U.S.) broadcast of The Walking Dead. As always, thank you for watching, and keep the comments coming. We appreciate all your support. #RIPSpoiler"

Were you spoiled?
