Mods: please move this question to Meta.

I just logged on from a new system and my reputation is down to 1 (used to be over 5k). What is going on?

**Edit I**: After posting I also note that a different user name is showing up associated with this question.

**Edit II**: my profile is completely clean, it seems a fresh new account was associated with my email address.

**Edit III**: [my old profile](http://askubuntu.com/users/177437/lu%c3%ads-de-sousa) still exists. However, every time I log on I end up in this new account.

**Edit IV**: The problem has been solved. When I log on I am now directed to the original account.
