An example for Facebook
"Since then the feature has aroused scrutiny over privacy concerns because the social plug-ins allow Facebook to track visitors to participating sites across the web, even if those visitors do not click the Like button,[3][4] are logged out of Facebook, or are not Facebook users at all.[5] The Like button is implemented similarly to an advertising network, and as more sites participate, gives Facebook a vast amount of information about who visits which sites, and when. When loading a web page which has the Like button enabled, the user's browser connects to Facebook's servers, which record the URL being visited, and the visitor's IP address and Facebook ID (if logged in). In June 2010 Facebook said it anonymizes this information after three months, and does not sell or otherwise share that information. The ACLU of Northern California cautioned website operators to be careful about installing Like buttons because "they're potentially telling Facebook about everyone who visits their web site, every time that person visits their web site."[4]"
