Abstract :
Many will agree that email is badly broken when it comes to protecting users from spam, especially spoofing. With the growing prevalence of social networking sites, the increasing visibility into end users’ social connections will make it easy for scammers to figure out how to better forge return addresses, among other problems. Those who create social networking infrastructures must be vigilant in defending such sites, to keep spam issues from becoming as prevalent there as they now are with email.
