A Survey on Spam Filtering for Online Social Networks

Spam is an unending headache associated with the phenomenon called the Internet. Most of us are spending a lot of time on Social networks where users build explicit networks and create virtual relationships. But users have less control over messages that are posted on their walls. Users may get spam (unwanted) messages. So, Social networks can be treated as double-edged sword. This survey presents different types of spam prevention and control mechanisms provided by the social networks and different techniques to improve user control.
