This is what has happened to me.
Before Orkut was affiliated with Google, i had an account with it and i had just populated the account details. After Google Inc acquired Orkut, i was unable to login to my Orkut account. I don't have any idea why i couldn't login to my Old Orkut account.
Recently, i asked one of my friend to invite me to join Orkut as it was through invitation only.
I could also create a new account in Orkut using same GMail account which should have stopped me in creating neew Orkut account as i had already one, but Google Orkut didn't !
When i created a new Google Orkut account, i populated with it my details, friends contacts and communities subcriptions.
Recently, Google Orkut asked my whether to use the same login which i use to for new Orkut account or merge it with GMail ID also - i mean to say you can login either Orkut userid / GMail id. I went with option of merging both the account - GMail and Orkut. The result was _really_ bad and ridiculous.
The new Orkut account had been replaced with old Orkut account.
After that whenever i login to Orkut, it use to go to my old Orkut account.
The new Orkut account also existed, i mean to say whoever refers to my new Orkut account, i use to get email for my GMail ID.
I wanted new orkut account as i had populated that which had taken my time and energy.
I deleted my Old Orkut account and my new Orkut account still exists, but i am unable to login to it or use it, but i get emails regarding it.
Summary - Google orkut has serious flaws :
* Why Google Orkut attached two orkut accounts to same GMail ID ?
* Why i am unable to login to the new Orkut account, as it still exists ?
* Why i get emails to my GMail ID for the new Orkut account ?
Totally, Google Orkut has lost my personal data.
