Facebook said Wednesday that it has stopped most of the spam that has flooded many users’ pages with pictures showing graphic sex and violence.

The social-networking company urged its 800 million-plus users to remain vigilant to keep their accounts from being hijacked.

Social-networking sites are popular targets for spammers because people are more likely to trust and share content that comes from their “friends.” This makes spam, scams and viruses easier to spread.
