Facebook is just like posting something on a Government Stamp Paper. You are liable for every like and dislike and can get prosecuted for the same. This has happened in reality. Facebook will regularly ask you for information which you only disclose at the time of opening a bank account. Infact, nobody should upload photos, IDs or whatsoever on any social media site. Boycott such websites which pester users repeatedly to upload their IDs. You can get your Banking Username Password back, but if your Facebook account is locked, this 200 Billion Company does not even have a customer care.
