I used to have a "reputation" of 1600+ and nearly 60 badges until one day when this platform inexplicably merged my account into one I opened a couple of years earlier and forgot about. Support said "there's nothing wrong" so I pretty much avoid the place now. It merged this email and some personal details into the other account that had virtually no history. For a while I could pull up both accounts, but after I kept bugging Support, the one with all of my history disappeared.
