I woke up this morning to find that my username had been changed (looks like to my google account username) and I lost all my tags. How did this happen? I have always been logging in with my facebook account. Furthermore, I woke up to find that my inbox was filled with 48 messages saying things like
"You have earned this badge for"....
Also, it seems that I am an entirely new user. I was user #5783 and now I am #38158. Can someone explain what's happening please?
I have changed my username back to what it was before I went to bed last night.
