Hundreds of Chinese have flooded U.S. President Barack Obama's Google-plus page with messages, after China seemingly unblocked the social networking service.
Google-plus has not been available in China since it was launched last year, apparently blocked by the communist nation's strict censorship system.
But in the past few days, access has been available, either because China lifted its blocks or because of a bug in the censorship system.
The comments to Obama center on freedom of expression and human rights, as well as everyday topics such as how to get U.S. green cards to work legally in the U.S.
