At this point, I strongly believe that social media spam prevention must occur at the social network software level. Social media sites can fight social spam by create algorithms that individualize user experience by interpreting relevancy through user relationships. Relationship data can come from what & how a user votes for, views, reads, recommends, bookmarks, or includes in his or her personal social network.
Utilizing OpenID Systems
Hopefullly, OpenID systems will allow social media sites to share user reputation, relevance, preference, and trust data with other social sites. More user data leads to the creation of more effective social media spam prevention tools, as well as increasingly relevant user experiences that give you exactly what you want.
