Like every morning I was going to check out skeptics, just to find out that my account wasn't recognized by the site, it worked on all other SE sites except this one, when I looked as a guest I can see my old questions are posted as user5169 , I'm not sure what happened to my account, as far as I know I haven't violate any policy or anything, apparently I was able to create a new account with the same ID but is not linking any of my previous activity, I don't have idea what could have caused this, any guidance would be appreciated.
Thanks.
