Some military base officials are warning service members to stay away from a series of rumored protests that could take place in major cities across the U.S. tomorrow.

The protests, which will supposedly be organized by the hacker group Anonymous, have been called “Day of Rage” and are supposed to occur in 37 cities, including Washington, D.C., Denver, Colorado, and St. Louis, Missouri.

Internet rumor debunker, however, reports that reports of the protests are likely an unfounded, very similar to a rumor circulated in 2014.

“Those inclined to question the likelihood that an actual ‘Day of Rage’ is being planned by Anonymous, we note that this rumor is virtually identical to one that was circulated two years earlier after the shooting of teenager Mike Brown in Ferguson, Missouri,” the site says.
