The same websites we all use to stay connected with friends, family, or people with common interests, hate groups are using to spread intolerance or worse, even incite violence. That's according to a new study by the Simon Wiesenthal Center which found a 25 percent rise in the last year alone, in what it labels as "problematic" groups popping up on social networks.

"There are over 10,000 problematic postings, websites, facebook, youtube stuff and back in 1995 not so long ago there was one hate site, so we're looking at an exponential explosion," said Rabbi Abraham Cooper of the Simon Wiesenthal Center. "But I want to emphasize there are two different areas. One is hate, you know if you're a Jew or black or Asian or gay there's a lot of hate online, but there's also another area of terrorist organizations that use the same technologies for command and control, recruitment, fundraising."

Authors of the study say it's particularly troubling now that hate has entered into the digital age. Ten or 20 years ago, if a hate group wanted to spread its message to the public, it had to convince a major media organization like the New York Times or CNN to do a story. But today, anyone, anywhere can post a hate message on the Internet and instantly it can be seen by anyone, anywhere in the world.

"You think Facebook, you have 200 million plus users that's a lot, unprecedented, we are in touch with Facebook, they are struggling to fulfill their own rules," said Rabbi Cooper.

In a statement, Facebook said, "Where hateful content is uploaded and reported, Facebook removes it and disables the responsible accounts. Many of the groups or pages that were shown to us by the Simon Wiesenthal Center earlier this year as part of their study had already been removed under Facebook's rules."

The Wiesenthal Center unveiled the study to a group of high school students hoping to appeal to them directly to recognize hate online, and take action rather than simply dismiss it.

"They teach us about this all the time, but we won't report it because we don't think of it as serious," said Juliette Frias, a student at Independence High School.

"You go on to a page, a pop-up, something hateful you tend to 'X' it out. It's a habit, you 'X' it out and ignore it," said Matthew Adames, a student at Independence High School.

If you notice hate while social networking, you're urged to either notify the site itself, like Facebook, or you can email the link to the Wiesenthal Center at ireport@Wiesenthal.com.
