Most services ask for your email address and/or recovery key to recover your account. LinkedIn, on the other hand, goes full surveillance mode. It wants my actual government ID to give access to my account.
If this was critical banking service, I would have understood. But it is freakin LinkedIn, the most I have got out of that place is actual lunatics.
This is the reason as to why I was a linkedin member until I tried to login the day after I created the account. Thanks but no thanks.
