BOSTON -- An elderly, arthritic mare in Massachusetts has become the subject of a virtual tug-of-war between the social networking site MySpace.com and a supporter of the horse.

A MySpace page devoted to the mare Quincy was taken down, put back up and taken down again, said Kendra Olson, its creator. Olson said MySpace gave her no explanation, reported WCVB-TV in Boston.

Olson has been leading an effort urging Quincy's owner, Elliot S. Saffran of Milford, Mass., to euthanize her and end her suffering.

In the six days it had been up, the page, which contained video of the 29-year-old mare struggling to walk, had received 3,256 views from people worldwide, dozens of whom left messages for Saffran to euthanize her.

After MySpace removed the page Friday, Olson put it back up again.

But by late afternoon, she received a message from MySpace warning that it was going to remove the page again.

"I'm not going to stop," Olson told the Boston Herald. "We're not vigilantes. We just want this horse, who has no voice, to be allowed to pass with some dignity and respect."

The Massachusetts Society for the Prevention of Cruelty to Animals visited Quincy in January and charged Saffran, 57, for "willfully subjecting the animal to suffer." He was charged with one count of animal cruelty.

However, Saffran, 57, told the Milford Daily News that the horse is not suffering.

"And we have veterinary reports that say it's not suffering," Saffran said, adding that he expects a jury trial.
