Corrections and clarifications: An earlier version of this story had the incorrect name of a bear advancing to the next round.

Fat Bear Week was rocked by a scandal this week as spam bots tried to get in on the action and cast fake votes.

The annual competition allows community members to vote for their favorite big bear in Alaska’s Katmai National Park.

“Like bears stuff their face with fish, our ballot box, too, has been stuffed,” the park wrote on its Facebook page Sunday. “It appears someone has decided to spam the Fat Bear Week poll, but fortunately it is easy for us to tell which votes are fraudulent.”

The park said the fraudulent votes came in for Holly. The park threw out the fake votes and updated the day’s totals, advancing bear 747 to the next round with 37,940 votes.

During the semifinal matchup between Holly and bear 747, the latter was leading for half of the day, said Mike Fitz, a naturalist from Explore.org, one of the contest organizers.

“His lead was a fairly sizable margin, but the vote ended up flipping within a short period of time,” Fitz said. “It’s uncommon to happen in Fat Bear Week, so when that happened, the website team for Explore.org took a look more closely at what was happening in the voting widget and ended up seeing that somebody was able to spam the vote.”

The fake votes totaled to “several thousand,” he told USA TODAY.
