An estimated 14.3 crore accounts on the popular social networking site Facebook may be false or duplicate, with a major chunk of them coming from developing markets like India and Turkey.
Facebook, which boasts of 119 crore accounts globally, in a US Securities and Exchange Commission (SEC) filing said it estimates up to 7.9 per cent accounts being duplicate, and up to 2.1 per cent and up to 1.2 per cent accounts being user-misclassified and un-desirable, respectively.
"We believe the percentage of accounts that are duplicate or false is meaningfully lower in developed markets such as the US or the UK and higher in developing markets such as India and Turkey," Facebook today said in a SEC filing.

The filing further said: "We estimate, for example, that duplicate accounts may have represented between approximately 4.3-7.9 per cent of our worldwide MAUs during the nine months ended September 30, 2013."
Duplicate account is the one, which a user maintains in addition to his or her principal account, it added.
"We also seek to identify false accounts, which we divide into two categories -- user-misclassified accounts and undesirable accounts.
"During the nine months ended September 30, 2013, for example, we estimate user-misclassified accounts may have represented between approximately 0.8-2.1 per cent of our worldwide MAUs and undesirable accounts may have represented between approximately 0.4-1.2 per cent of our worldwide MAUs," the filing said.
User-misclassified accounts is where users create personal profiles for a business, organisation or non-human entity such as a pet (such entities are permitted on Facebook using a Page rather than a personal profile under its terms of service, it added.
Undesirable accounts, which represent user profiles that Facebook determines are intended to be used for purposes that violate
