Somewhere, perhaps in a boggy retreat from an England ablaze, anarchist and comic author Alan Moore must be smiling beneath his whiskers. Or, more precisely, grinning a sly, wet smirk of intellectual satisfaction worthy of Guy Fawkes.

Moore, of course, is the legendary writer who co-created the great “V for Vendetta” comic with illustrator David Lloyd. They gave their dramatic terrorist of a title character a Guy Fawkes mask — a symbol of the British revolutionary who died at the gallows for his part in the Nov. 5, 1605, plot to blow up the House of Lords.

The “hacktivist” group Anonymous has donned the Guy Fawkes mask as a symbol of revolt. And Anonymous has just resurfaced in the news, as media reports say Anonymous plans to blow up Facebook Nov. 5 — aka the still-celebrated “Guy Fawkes Day” (or Night).

“The hackers have set the date for Facebook’s demise as November 5, 2011,” Rosie Gray of the Village Voice wrote Tuesday. “The reason? Ironically, they’re worried about privacy.” (Our Faster Forward blog notes that last year, Facebook co-founder Mark Zuckerberg wrote in The Post: “We do not and never will sell any of your information to anyone.”)

Anonymous reportedly posted a video [below] about its own gunpowder of a plot, dubbed Operation Facebook. Some outlets, however, including ZDNet and PC Magazine, have reported that the larger Anonymous group does not support this plot and that hackers with ties to the group are working to carry it out. And @AnonOps tweeted that “#OpFacebook is being organised by some Anons. This does not necessarily mean that all of #Anonymous agrees with it.”

(Update: Gawker reports how an elaborate chain of events may have unfolded.)

As authorities investigate and the world wonders whether a lone hackitivist group could actually dismantle all of Facebook, Comic Riffs today recalls Hugo Weaving’s “V” performance and his Remember the 5th of November speechifying.

This is a clip, by the way, at which Moore likely does not smile or smirk with satisfaction. It was the “Watchmen” and “League of Extraordinary Gentlemen” author, after all — no fan of Hollywood’s “spoon-fed” adaptations of comics — who once said: “I despise the comic industry, but I will always love the comic medium.”
