According to researchers, the social networking giant will become the world's biggest virtual graveyard by the end of this century as there will be more profiles of dead people than of living users.

"Social media website Facebook, which currently has 1.5 billion users worldwide, will turn into the world's biggest virtual graveyard by 2098," Dailymail.co.uk quoted statistician Hachem Sadikki from University of Massachusetts as saying.

This will happen because the website refuses to delete dead users and instead turns the account into a "memorialised" version."Facebook's refusal to automatically delete dead users and the plateauing membership of the site means that the living will be outnumbered sooner than you might think," the report said.

Sadikki, PhD candidate in statistics at University of Massachusetts, said he worked out the figure by assuming that Facebook's growth will begin to slow soon. A blogging company Digital Beyond has claimed that nearly 970,000 Facebook users will die this year alone across the world which is far more as compared to 385,968 in 2010 and 580,000 in 2012.

Sadikki also assumed that the social media website will retain its existing policy on how to handle dead users.The website's policy has attracted criticism from users in the past as it showed the photos of dead ones in its "year in review" videos (till 2015).
