Xeroxed posters advertising a website purportedly set up by global online activist group Anonymous appeared on trees and light poles up and down Avenida Del Mar in San Clemente over the weekend weekend.

The posters have appeared throughout downtown San Clemente and at locations on Avenida Pico, as well as other cities in Orange County. The campaign is apparently worldwide: Members of Anonymous have been spamming top-rated YouTube videos as well as posting signs.

The posters send people to whatis-theplan.org, which has information and videos about a vague three-phase plan called Operation Onslaught. The "plan" apparently involves acts of protest against what organizers consider the corruption of corporations and government regimes worldwide. "Corporate bigwigs live the highlife as they rape the land we all share," says an unidentified figure—cloaked and wearing a mask—in a video on the site. "We grow up being told who to be … We have been consumed."

The video goes on to cite statistics about military spending and poverty and abuse of power by police. The site encourages people to sign up to participate in a system of discussion forums.

The Anonymous group is linked to the "hacktivist" shutdown of PayPal and major banking websites after those sites refused to funnel money to Wikileaks, which had posted classified documents over the winter.

Federal authorities arrested 14 alleged members of the group on suspicion of perpetrating the "denial of service" attacks—a method of shutting down a website by flooding it with requests for service.
