What information have companies collected about you? Your attention data, behaviors, demographics, clickstream patterns, etc… and more.

Which companies have personal data about you?
Where is it stored? Who has control of it?
Or rather.. who have they sold it to? And what will they do with it?

MANY companies now maintain a large array of personal info about anyone who uses their website or other services. Most companies use personal data to target products, advertisements and other offers to consumers.

Pierre-Guillaume Wielezynski of the World Bank, posted about a future model of user-centric ad-serving where corporations partner with individuals to access their personal information.

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.
