As an "antisocial" (never had a Facebook/[other social network] account and never will) I see this as expected behaviour. They need you inside to access your data. They need you to interact more with them to gather more data. If you see your friends taking drugs, you feel the (social?) pressure to try them too. If somebody (the drug seller) tells you that all your friends are into drugs, you don't feel guilty if you try them.
